This patch makes the MallocSizeOf stuff in Stylo work more like the HeapSizeOf stuff already in Servo, except better. In particular, it adds deriving support for MallocSizeOf, which will make it easier to improve coverage. The patch does the following. - Combines servo/components/style/stylesheets/memory.rs and the heapsize crate into a new crate, malloc_size_of. - Forks the heapsize_derive crate, calling it malloc_size_of, so that MallocSizeOf can be derived. - Both the new crates have MIT/Apache licenses, like heapsize, in case they are incorporated into heapsize in the future. - Renames the methods within MallocSizeOf and the related traits so they are more concise. - Removes MallocSizeOfWithGuard. - Adds `derive(MallocSizeOf)` to a lot of types, in some cases replacing an equivalent or almost-equivalent hand-written implementation. - Adds stuff so that Rc/Arc can be handled properly.
rust-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.
(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 itself.
