// Return a new NotSupportedError and terminate this algorithm.
// Step 6. Let normalizedAlgorithm be the result of converting the ECMAScript object
// represented by alg to the IDL dictionary type desiredType, as defined by [WebIDL].
// Step 7. Set the name attribute of normalizedAlgorithm to algName.
// Step 8. If an error occurred, return the error and terminate this algorithm.
// Step 9. Let dictionaries be a list consisting of the IDL dictionary type desiredType
// and all of desiredType's inherited dictionaries, in order from least to most
// derived.
// Step 10. For each dictionary dictionary in dictionaries:
// Step 10.1. For each dictionary member member declared on dictionary, in order:
// Step 10.1.1. Let key be the identifier of member.
// Step 10.1.2. Let idlValue be the value of the dictionary member with key
// name of key on normalizedAlgorithm.
// Step 10.1.3.
// If member is of the type BufferSource and is present:
// Set the dictionary member on normalizedAlgorithm with key name key
// to the result of getting a copy of the bytes held by idlValue,
// replacing the current value.
// If member is of the type HashAlgorithmIdentifier:
// Set the dictionary member on normalizedAlgorithm with key name key
// to the result of normalizing an algorithm, with the alg set to
// idlValue and the op set to "digest".
// If member is of the type AlgorithmIdentifier:
// Set the dictionary member on normalizedAlgorithm with key name key
// to the result of normalizing an algorithm, with the alg set to
// idlValue and the op set to the operation defined by the
// specification that defines the algorithm identified by algName.
//
// NOTE: Step 7 is done by writing algName back to the name attribute of the JS object
// before dictionary conversion in Step 6, in order to streamline the conversion. Step
// 9 and 10 are done by the calling `TryIntoWithCx::try_into_with_cx` within the trait

// <https://w3c.github.io/webcrypto/#dfn-supportedAlgorithms>
//
// We implement the internal object
// [supportedAlgorithms](https://w3c.github.io/webcrypto/#dfn-supportedAlgorithms) for algorithm
// registration, in the following way.
//
// For each operation v in the list of [supported
// operations](https://w3c.github.io/webcrypto/#supported-operation), we define a struct to
// represent it, which acts a key of the internal object supportedAlgorithms.
//
// We then implement the [`Operation`] trait for these structs. When implementing the trait for
// each of these structs, we set the associated type [`RegisteredAlgorithm`] of [`Operation`] to an
// enum as the value of the operation v in supportedAlgorithms. The enum lists all algorithhms
// supporting the operation v as its variants.
//
// To [define an algorithm](https://w3c.github.io/webcrypto/#concept-define-an-algorithm), each
// variant in the enum has an inner type corresponding to the desired input IDL dictionary type for
// the supported algorithm represented by the variant. Moreover, the enum also need to implement
// the [`NormalizedAlgorithm`] trait since it is used as the output of
// [`normalize_algorithm`].
//
// For example, we define the [`EncryptOperation`] struct to represent the "encrypt" operation, and
// implement the [`Operation`] trait for it. The associated type [`RegisteredAlgorithm`] of
// [`Operation`] is set to the [`EncryptAlgorithm`] enum, whose variants are cryptographic
// algorithms that support the "encrypt" operation. The variant [`EncryptAlgorithm::AesCtr`] has an
// inner type [`SubtleAesCtrParams`] since the desired input IDL dictionary type for "encrypt"
// operation of AES-CTR algorithm is the `AesCtrParams` dictionary. The [`EncryptAlgorithm`] enum
// also implements the [`NormalizedAlgorithm`] trait accordingly.
//
