A few small changes here:
* `ArrayBufferView` and `BufferSource` are expanded to themselves plus
`Uint8ArrayMut` instead of `Object` to ensure we keep the original type.
* Generating an argument type for `ArrayBufferView`, `BufferSource`, and
`Object` all now generate shared references instead of owned objects, which is
a little more consistent with the other interface types.
* Gate `web-sys` APIs on activated features
Currently the compile times of `web-sys` are unfortunately prohibitive,
increasing the barrier to using it. This commit updates the crate to instead
have all APIs gated by a set of Cargo features which affect what bindings are
generated at compile time (and which are then compiled by rustc). It's
significantly faster to activate only a handful of features vs all thousand of
them!
A magical env var is added to print the list of all features that should be
generated, and then necessary logic is added to ferry features from the build
script to the webidl crate which then uses that as a filter to remove items
after parsing. Currently parsing is pretty speedy so we'll unconditionally parse
all WebIDL files, but this may change in the future!
For now this will make the `web-sys` crate a bit less ergonomic to use as lots
of features will need to be specified, but it should make it much more
approachable in terms of first-user experience with compile times.
* Fix AppVeyor testing web-sys
* FIx a typo
* Udpate feature listings from rebase conflicts
* Add some crate docs and such
This commit reimplements how we disambiguate function names on overloading.
Previously functions would be first be disambiguated if they had multiple
instances of the same name, and *then* functions would be disambiguated
aftewards by if their arguments expanded to more than one type to generate.
This commit instead collects everything into one list during the first pass.
This one list contains all signatures known for a given name. Later this list is
walked in one pass to generate all methods necessary, expanding names all at
once instead of two steps.
This should improve the naming of methods across multiple functions which also
have optional arguments. Support in this commit is just enough for namespaces,
but following commits will update the strategy for mixins/interfaces.
Additionally only new code was added in this commit which duplicates a lot of
functionality, but subsequent commits will remove the old code that will
eventually no longer be used.
This commit refactors the lowest-level primitive for creating functions into a
new `create_one_function` function. This doesn't take into account overloading
but is suitable for things like `create_{getter,setter}`. Eventually the
overloading will be implemented in terms of this function.
This commit refactors WebIDL code generation to walk over the fields of
`FirstPassRecord` instead of walking the AST again. This helps remove
redundancies like checking `is_chrome_only` as well as revisiting partial
interfaces and such. This should make it more clear that the first pass's job is
to walk the AST and collect all relevant information, while the codegen pass is
purely about appending items to a `Program`.
Additionally this refactoring will also soon be used to prepare different data
structures for operation overloadings, avoiding the need to walk those ASTs
twice.
