+//! # Inline Formatting Context Layout
+//!
+//! Inline layout is divided into three phases:
+//!
+//! 1. Box Tree Construction
+//! 2. Box to Line Layout
+//! 3. Line to Fragment Layout
+//!
+//! The first phase happens during normal box tree constrution, while the second two phases happen
+//! during fragment tree construction (sometimes called just "layout").
+//!
+//! ## Box Tree Construction
+//!
+//! During box tree construction, DOM elements are transformed into a box tree. This phase collects
+//! all of the inline boxes, text, atomic inline elements (boxes with `display: inline-block` or
+//! `display: inline-table` as well as things like images and canvas), absolutely positioned blocks,
+//! and floated blocks.
+//!
+//! During the last part of this phase, whitespace is collapsed and text is segmented into
+//! [`TextRun`]s based on script, chosen font, and line breaking opportunities. In addition, default
+//! fonts are selected for every inline box. Each segment of text is shaped using HarfBuzz and
+//! turned into a series of glyphs, which all have a size and a position relative to the origin of
+//! the [`TextRun`] (calculated in later phases).
+//!
+//! The code for this phase is mainly in `construct.rs`, but text handling can also be found in
+//! `text_runs.rs.`
+//!
+//! ## Box to Line Layout
+//!
+//! During the first phase of fragment tree construction, box tree items are laid out into
+//! [`LineItem`]s and fragmented based on line boundaries. This is where line breaking happens. This
+//! part of layout fragments boxes and their contents across multiple lines while positioning floats
+//! and making sure non-floated contents flow around them. In addition, all atomic elements are laid
+//! out, which may descend into their respective trees and create fragments. Finally, absolutely
+//! positioned content is collected in order to later hoist it to the containing block for
+//! absolutes.
+//!
+//! Note that during this phase, layout does not know the final block position of content. Only
+//! during line to fragment layout, are the final block positions calculated based on the line's
+//! final content and its vertical alignment. Instead, positions and line heights are calculated
+//! relative to the line's final baseline which will be determined in the final phase.
+//!
+//! [`LineItem`]s represent a particular set of content on a line. Currently this is represented by
+//! a linear series of items that describe the line's hierarchy of inline boxes and content. The
+//! item types are:
+//!
+//!  - [`LineItem::TextRun`]
+//!  - [`LineItem::StartInlineBox`]
+//!  - [`LineItem::EndInlineBox`]
+//!  - [`LineItem::Atomic`]
+//!  - [`LineItem::AbsolutelyPositioned`]
+//!  - [`LineItem::Float`]
+//!
+//! The code for this can be found by looking for methods of the form `layout_into_line_item()`.
+//!
+//! ## Line to Fragment Layout
+//!
+//! During the second phase of fragment tree construction, the final block position of [`LineItem`]s
+//! is calculated and they are converted into [`Fragment`]s. After layout, the [`LineItem`]s are
+//! discarded and the new fragments are incorporated into the fragment tree. The final static
+//! position of absolutely positioned content is calculated and it is hoisted to its containing
+//! block via [`PositioningContext`].
+//!
+//! The code for this phase, can mainly be found in `line.rs`.

-//! A crate for measuring the heap usage of data structures in a way that
-//! integrates with Firefox's memory reporting, particularly the use of
-//! mozjemalloc and DMD. In particular, it has the following features.
-//! - It isn't bound to a particular heap allocator.
-//! - It provides traits for both "shallow" and "deep" measurement, which gives
-//!   flexibility in the cases where the traits can't be used.
-//! - It allows for measuring blocks even when only an interior pointer can be
-//!   obtained for heap allocations, e.g. `HashSet` and `HashMap`. (This relies
-//!   on the heap allocator having suitable support, which mozjemalloc has.)
-//! - It allows handling of types like `Rc` and `Arc` by providing traits that
-//!   are different to the ones for non-graph structures.
-//!
-//! Suggested uses are as follows.
-//! - When possible, use the `MallocSizeOf` trait. (Deriving support is
-//!   provided by the `malloc_size_of_derive` crate.)
-//! - If you need an additional synchronization argument, provide a function
-//!   that is like the standard trait method, but with the extra argument.
-//! - If you need multiple measurements for a type, provide a function named
-//!   `add_size_of` that takes a mutable reference to a struct that contains
-//!   the multiple measurement fields.
-//! - When deep measurement (via `MallocSizeOf`) cannot be implemented for a
-//!   type, shallow measurement (via `MallocShallowSizeOf`) in combination with
-//!   iteration can be a useful substitute.
-//! - `Rc` and `Arc` are always tricky, which is why `MallocSizeOf` is not (and
-//!   should not be) implemented for them.
-//! - If an `Rc` or `Arc` is known to be a "primary" reference and can always
-//!   be measured, it should be measured via the `MallocUnconditionalSizeOf`
-//!   trait.
-//! - If an `Rc` or `Arc` should be measured only if it hasn't been seen
-//!   before, it should be measured via the `MallocConditionalSizeOf` trait.
-//! - Using universal function call syntax is a good idea when measuring boxed
-//!   fields in structs, because it makes it clear that the Box is being
-//!   measured as well as the thing it points to. E.g.
-//!   `<Box<_> as MallocSizeOf>::size_of(field, ops)`.

-* [![Build Status](https://travis-ci.com/servo/rust-selectors.svg?branch=master)](
-  https://travis-ci.com/servo/rust-selectors)
-* [Documentation](https://docs.rs/selectors/)
-* [crates.io](https://crates.io/crates/selectors)
-
-CSS Selectors library for Rust.
-Includes parsing and serilization of selectors,
-as well as matching against a generic tree of elements.
-Pseudo-elements and most pseudo-classes are generic as well.
-
-**Warning:** breaking changes are made to this library fairly frequently
-(13 times in 2016, for example).
-However you can use this crate without updating it that often,
-old versions stay available on crates.io and Cargo will only automatically update
-to versions that are numbered as compatible.
-
-To see how to use this library with your own tree representation,
-see [Kuchiki’s `src/select.rs`](https://github.com/kuchiki-rs/kuchiki/blob/master/src/select.rs).
-(Note however that Kuchiki is not always up to date with the latest rust-selectors version,
-so that code may need to be tweaked.)
-If you don’t already have a tree data structure,
-consider using [Kuchiki](https://github.com/kuchiki-rs/kuchiki) itself.

-/// A counting Bloom filter with parameterized storage to handle
-/// counters of different sizes.  For now we assume that having two hash
-/// functions is enough, but we may revisit that decision later.
-///
-/// The filter uses an array with 2**KeySize entries.
-///
-/// Assuming a well-distributed hash function, a Bloom filter with
-/// array size M containing N elements and
-/// using k hash function has expected false positive rate exactly
-///
-/// $  (1 - (1 - 1/M)^{kN})^k  $
-///
-/// because each array slot has a
-///
-/// $  (1 - 1/M)^{kN}  $
-///
-/// chance of being 0, and the expected false positive rate is the
-/// probability that all of the k hash functions will hit a nonzero
-/// slot.
-///
-/// For reasonable assumptions (M large, kN large, which should both
-/// hold if we're worried about false positives) about M and kN this
-/// becomes approximately
-///
-/// $$  (1 - \exp(-kN/M))^k   $$
-///
-/// For our special case of k == 2, that's $(1 - \exp(-2N/M))^2$,
-/// or in other words
-///
-/// $$    N/M = -0.5 * \ln(1 - \sqrt(r))   $$
-///
-/// where r is the false positive rate.  This can be used to compute
-/// the desired KeySize for a given load N and false positive rate r.
-///
-/// If N/M is assumed small, then the false positive rate can
-/// further be approximated as 4*N^2/M^2.  So increasing KeySize by
-/// 1, which doubles M, reduces the false positive rate by about a
-/// factor of 4, and a false positive rate of 1% corresponds to
-/// about M/N == 20.
-///
-/// What this means in practice is that for a few hundred keys using a
-/// KeySize of 12 gives false positive rates on the order of 0.25-4%.
-///
-/// Similarly, using a KeySize of 10 would lead to a 4% false
-/// positive rate for N == 100 and to quite bad false positive
-/// rates for larger N.

-//! Helper module to build up a selector safely and efficiently.
-//!
-//! Our selector representation is designed to optimize matching, and has
-//! several requirements:
-//! * All simple selectors and combinators are stored inline in the same buffer
-//!   as Component instances.
-//! * We store the top-level compound selectors from right to left, i.e. in
-//!   matching order.
-//! * We store the simple selectors for each combinator from left to right, so
-//!   that we match the cheaper simple selectors first.
-//!
-//! Meeting all these constraints without extra memmove traffic during parsing
-//! is non-trivial. This module encapsulates those details and presents an
-//! easy-to-use API for the parser.

-//! Fork of Arc for Servo. This has the following advantages over std::sync::Arc:
-//!
-//! * We don't waste storage on the weak reference count.
-//! * We don't do extra RMU operations to handle the possibility of weak references.
-//! * We can experiment with arena allocation (todo).
-//! * We can add methods to support our custom use cases [1].
-//! * We have support for dynamically-sized types (see from_header_and_iter).
-//! * We have support for thin arcs to unsized types (see ThinArc).
-//! * We have support for references to static data, which don't do any
-//!   refcounting.
-//!
-//! [1]: https://bugzilla.mozilla.org/show_bug.cgi?id=1360883

-/// An `Arc` that is known to be uniquely owned
-///
-/// When `Arc`s are constructed, they are known to be
-/// uniquely owned. In such a case it is safe to mutate
-/// the contents of the `Arc`. Normally, one would just handle
-/// this by mutating the data on the stack before allocating the
-/// `Arc`, however it's possible the data is large or unsized
-/// and you need to heap-allocate it earlier in such a way
-/// that it can be freely converted into a regular `Arc` once you're
-/// done.
-///
-/// `UniqueArc` exists for this purpose, when constructed it performs
-/// the same allocations necessary for an `Arc`, however it allows mutable access.
-/// Once the mutation is finished, you can call `.shareable()` and get a regular `Arc`
-/// out of it.

-///
-/// The constraints for Servo's style system are a bit different compared to

-///
-/// This implies that we need to track a bit more state than other browsers to
-/// ensure we're doing the correct thing during the traversal, and being able to

-/// match the previous element we've styled.

-/// the previous one), but in the case of work-stealing, we may needed to push
-/// and pop multiple elements.

-/// In order to compute restyle hints, we perform a selector match against a
-/// list of partial selectors whose rightmost simple selector may be sensitive
-/// to the thing being changed. We do this matching twice, once for the element
-/// as it exists now and once for the element as it existed at the time of the
-/// last restyle. If the results of the selector match differ, that means that
-/// the given partial selector is sensitive to the change, and we compute a
-/// restyle hint based on its combinator.
-///
-/// In order to run selector matching against the old element state, we generate
-/// a wrapper for the element which claims to have the old state. This is the
-/// ElementWrapper logic below.
-///
-/// Gecko does this differently for element states, and passes a mask called
-/// mStateMask, which indicates the states that need to be ignored during
-/// selector matching. This saves an ElementWrapper allocation and an additional
-/// selector match call at the expense of additional complexity inside the
-/// selector matching logic. This only works for boolean states though, so we
-/// still need to take the ElementWrapper approach for attribute-dependent
-/// style. So we do it the same both ways for now to reduce complexity, but it's
-/// worth measuring the performance impact (if any) of the mStateMask approach.

-        //    still in the list, since we remove the dependencies that
-        //    aren't from the lists for our children / siblings.
-        //
-        // To go through an example, let's imagine we are processing a

-        //
-        //   <div><address><div><div/></div></address></div>

-        //
-        //   [div div div, div div]
-        //
-        // With the first of them marked as `matched`.
-        //
-        // When we process the <address> child, we don't match any of
-        // them, so both invalidations go untouched to our children.
-        //
-        // When we process the second <div>, we match _both_
-        // invalidations.
-        //
-        // However, when matching the first, we can tell it's been
-        // matched, and not push the corresponding `div div`
-        // invalidation, since we know it's necessarily already on the
-        // list.

-//! Implements parallel traversal over the DOM tree.
-//!
-//! This traversal is based on Rayon, and therefore its safety is largely
-//! verified by the type system.
-//!
-//! The primary trickiness and fine print for the above relates to the
-//! thread safety of the DOM nodes themselves. Accessing a DOM element
-//! concurrently on multiple threads is actually mostly "safe", since all
-//! the mutable state is protected by an AtomicRefCell, and so we'll
-//! generally panic if something goes wrong. Still, we try to to enforce our
-//! thread invariants at compile time whenever possible. As such, TNode and
-//! TElement are not Send, so ordinary style system code cannot accidentally
-//! share them with other threads. In the parallel traversal, we explicitly
-//! invoke |unsafe { SendNode::new(n) }| to put nodes in containers that may
-//! be sent to other threads. This occurs in only a handful of places and is
-//! easy to grep for. At the time of this writing, there is no other unsafe
-//! code in the parallel traversal.

-// FIXME (Manishearth): Add computed_value_as_specified argument
-// and handle the empty case correctly
-<%doc>
-    To be used in cases where we have a grammar like "<thing> [ , <thing> ]*".
-
-    Setting allow_empty to False allows for cases where the vector
-    is empty. The grammar for these is usually "none | <thing> [ , <thing> ]*".
-    We assume that the default/initial value is an empty vector for these.
-    `initial_value` need not be defined for these.
-</%doc>
-
-// The setup here is roughly:
-//
-//  * UnderlyingList is the list that is stored in the computed value. This may
-//    be a shared ArcSlice if the property is inherited.
-//  * UnderlyingOwnedList is the list that is used for animation.
-//  * Specified values always use OwnedSlice, since it's more compact.
-//  * computed_value::List is just a convenient alias that you can use for the
-//    computed value list, since this is in the computed_value module.
-//
-// If simple_vector_bindings is true, then we don't use the complex iterator
-// machinery and set_foo_from, and just compute the value like any other
-// longhand.

-/// The rule tree, the structure servo uses to preserve the results of selector

-///
-/// This is organized as a tree of rules. When a node matches a set of rules,
-/// they're inserted in order in the tree, starting with the less specific one.
-///
-/// When a rule is inserted in the tree, other elements may share the path up to
-/// a given rule. If that's the case, we don't duplicate child nodes, but share
-/// them.
-///
-/// When the rule node refcount drops to zero, it doesn't get freed. It gets
-/// instead put into a free list, and it is potentially GC'd after a while.
-///
-/// That way, a rule node that represents a likely-to-match-again rule (like a
-/// :hover rule) can be reused if we haven't GC'd it yet.

-/// "a .foo .bar.baz" would go into the set of selectors corresponding to

-///
-/// Because we match selectors right-to-left (i.e., moving up the tree
-/// from an element), we need to compare the last simple selector in the
-/// selector with the element.
-///
-/// So, if an element has ID "id1" and classes "foo" and "bar", then all
-/// the rules it matches will have their last simple selector starting

-/// Hence, the union of the rules keyed on each of element's classes, ID,
-/// element name, etc. will contain the Selectors that actually match that
-/// element.

-/// We use a 1-entry SmallVec to avoid a separate heap allocation in the case

-//! Code related to the style sharing cache, an optimization that allows similar
-//! nodes to share style without having to run selector matching twice.
-//!
-//! The basic setup is as follows.  We have an LRU cache of style sharing
-//! candidates.  When we try to style a target element, we first check whether
-//! we can quickly determine that styles match something in this cache, and if
-//! so we just use the cached style information.  This check is done with a
-//! StyleBloom filter set up for the target element, which may not be a correct
-//! state for the cached candidate element if they're cousins instead of
-//! siblings.
-//!
-//! The complicated part is determining that styles match.  This is subject to
-//! the following constraints:
-//!
-//! 1) The target and candidate must be inheriting the same styles.
-//! 2) The target and candidate must have exactly the same rules matching them.
-//! 3) The target and candidate must have exactly the same non-selector-based
-//!    style information (inline styles, presentation hints).
-//! 4) The target and candidate must have exactly the same rules matching their
-//!    pseudo-elements, because an element's style data points to the style
-//!    data for its pseudo-elements.
-//!
-//! These constraints are satisfied in the following ways:
-//!
-//! * We check that the parents of the target and the candidate have the same
-//!   computed style.  This addresses constraint 1.
-//!
-//! * We check that the target and candidate have the same inline style and
-//!   presentation hint declarations.  This addresses constraint 3.
-//!
-//! * We ensure that a target matches a candidate only if they have the same
-//!   matching result for all selectors that target either elements or the
-//!   originating elements of pseudo-elements.  This addresses constraint 4
-//!   (because it prevents a target that has pseudo-element styles from matching
-//!   a candidate that has different pseudo-element styles) as well as
-//!   constraint 2.
-//!
-//! The actual checks that ensure that elements match the same rules are
-//! conceptually split up into two pieces.  First, we do various checks on
-//! elements that make sure that the set of possible rules in all selector maps
-//! in the stylist (for normal styling and for pseudo-elements) that might match
-//! the two elements is the same.  For example, we enforce that the target and
-//! candidate must have the same localname and namespace.  Second, we have a
-//! selector map of "revalidation selectors" that the stylist maintains that we
-//! actually match against the target and candidate and then check whether the
-//! two sets of results were the same.  Due to the up-front selector map checks,
-//! we know that the target and candidate will be matched against the same exact
-//! set of revalidation selectors, so the match result arrays can be compared
-//! directly.
-//!
-//! It's very important that a selector be added to the set of revalidation
-//! selectors any time there are two elements that could pass all the up-front
-//! checks but match differently against some ComplexSelector in the selector.
-//! If that happens, then they can have descendants that might themselves pass
-//! the up-front checks but would have different matching results for the
-//! selector in question.  In this case, "descendants" includes pseudo-elements,
-//! so there is a single selector map of revalidation selectors that includes
-//! both selectors targeting elements and selectors targeting pseudo-element
-//! originating elements.  We ensure that the pseudo-element parts of all these
-//! selectors are effectively stripped off, so that matching them all against
-//! elements makes sense.

-//! `<length-percentage>` computed values, and related ones.
-//!
-//! The over-all design is a tagged pointer, with the lower bits of the pointer
-//! being non-zero if it is a non-calc value.
-//!
-//! It is expected to take 64 bits both in x86 and x86-64. This is implemented
-//! as a `union`, with 4 different variants:
-//!
-//!  * The length and percentage variants have a { tag, f32 } (effectively)
-//!    layout. The tag has to overlap with the lower 2 bits of the calc variant.
-//!
-//!  * The `calc()` variant is a { tag, pointer } in x86 (so same as the
-//!    others), or just a { pointer } in x86-64 (so that the two bits of the tag
-//!    can be obtained from the lower bits of the pointer).
-//!
-//!  * There's a `tag` variant just to make clear when only the tag is intended
-//!    to be read. Note that the tag needs to be masked always by `TAG_MASK`, to
-//!    deal with the pointer variant in x86-64.
-//!
-//! The assertions in the constructor methods ensure that the tag getter matches
-//! our expectations.

-//! Helper types and traits for the handling of CSS values.
-
-use app_units::Au;

-use servo_arc::Arc;
-use std::fmt::{self, Write};
-
-/// Serialises a value according to its CSS representation.
-///
-/// This trait is implemented for `str` and its friends, serialising the string
-/// contents as a CSS quoted string.
-///
-/// This trait is derivable with `#[derive(ToCss)]`, with the following behaviour:
-/// * unit variants get serialised as the `snake-case` representation
-///   of their name;
-/// * unit variants whose name starts with "Moz" or "Webkit" are prepended
-///   with a "-";
-/// * if `#[css(comma)]` is found on a variant, its fields are separated by
-///   commas, otherwise, by spaces;
-/// * if `#[css(function)]` is found on a variant, the variant name gets
-///   serialised like unit variants and its fields are surrounded by parentheses;
-/// * if `#[css(iterable)]` is found on a function variant, that variant needs
-///   to have a single member, and that member needs to be iterable. The
-///   iterable will be serialized as the arguments for the function;
-/// * an iterable field can also be annotated with `#[css(if_empty = "foo")]`
-///   to print `"foo"` if the iterator is empty;
-/// * if `#[css(dimension)]` is found on a variant, that variant needs
-///   to have a single member. The variant would be serialized as a CSS
-///   dimension token, like: <member><identifier>;
-/// * if `#[css(skip)]` is found on a field, the `ToCss` call for that field
-///   is skipped;
-/// * if `#[css(skip_if = "function")]` is found on a field, the `ToCss` call
-///   for that field is skipped if `function` returns true. This function is
-///   provided the field as an argument;
-/// * if `#[css(contextual_skip_if = "function")]` is found on a field, the
-///   `ToCss` call for that field is skipped if `function` returns true. This
-///   function is given all the fields in the current struct or variant as an
-///   argument;
-/// * `#[css(represents_keyword)]` can be used on bool fields in order to
-///   serialize the field name if the field is true, or nothing otherwise.  It
-///   also collects those keywords for `SpecifiedValueInfo`.
-/// * `#[css(bitflags(single="", mixed="", validate="", overlapping_bits)]` can
-///   be used to derive parse / serialize / etc on bitflags. The rules for parsing
-///   bitflags are the following:
-///
-///     * `single` flags can only appear on their own. It's common that bitflags
-///       properties at least have one such value like `none` or `auto`.
-///     * `mixed` properties can appear mixed together, but not along any other
-///       flag that shares a bit with itself. For example, if you have three
-///       bitflags like:
-///
-///         FOO = 1 << 0;
-///         BAR = 1 << 1;
-///         BAZ = 1 << 2;
-///         BAZZ = BAR | BAZ;
-///
-///       Then the following combinations won't be valid:
-///
-///         * foo foo: (every flag shares a bit with itself)
-///         * bar bazz: (bazz shares a bit with bar)
-///
-///       But `bar baz` will be valid, as they don't share bits, and so would
-///       `foo` with any other flag, or `bazz` on its own.
-///    * `overlapping_bits` enables some tracking during serialization of mixed
-///       flags to avoid serializing variants that can subsume other variants.
-///       In the example above, you could do:
-///         mixed="foo,bazz,bar,baz", overlapping_bits
-///       to ensure that if bazz is serialized, bar and baz aren't, even though
-///       their bits are set. Note that the serialization order is canonical,
-///       and thus depends on the order you specify the flags in.
-///
-/// * finally, one can put `#[css(derive_debug)]` on the whole type, to
-///   implement `Debug` by a single call to `ToCss::to_css`.
