I think these might all be from before WebIDL mixins existed. Either way,
multiple inheritance of interfaces that don't have exposed interface objects is
equivalent to mixins.
This commit adds support for two different features of the "special" operations
in WebIDL. First, it implements the desugaring [described by WebIDL][1] where
this:
interface Dictionary {
getter double getProperty(DOMString propertyName);
setter void setProperty(DOMString propertyName, double propertyValue);
};
becomes ...
interface Dictionary {
double getProperty(DOMString propertyName);
void setProperty(DOMString propertyName, double propertyValue);
getter double (DOMString propertyName);
setter void (DOMString propertyName, double propertyValue);
};
where specifically a named `getter` generates both a getter and a named
function.
Second it implements the distinction between two different types of getters in
WebIDL, described as:
> Getters and setters come in two varieties: ones that take a DOMString as a
> property name, known as named property getters and named property setters, and
> ones that take an unsigned long as a property index, known as indexed property
> getters and indexed property setters.
The name `get` is given to DOMString arguments, and the name `get_idx` is given
to index property getters.

This commit migrates the `wasm-bindgen-webidl` crate from the `webidl` parser to
`weedle`. The main rationale for doing this is that `webidl` depends on
`lalrpop`, which is quite a large dependency and takes a good deal of time to
compile. The `weedle` crate, however, depends on `nom` and is much faster to
compile.
Almost all translations were pretty straightforward. Some abstractions changed
and/or were introduced in this commit when moving to `weedle` like the
`ToSynType` trait, but otherwise the generated bindings should be the same. It's
been verified that the `weedle`-generated bindings are exactly the same as the
`webidl`-generated bindings, with the one exception of `weedle` generates one
more method, `WebGpuCommandEncoder::transition_buffer`. It's not clear currently
why `webidl` didn't generate this method, as its [idl] is pretty straightforward!
This commit is using a [fork] of `weedle` currently which has a number of fixes
for parsing our WebIDL, although all the fixes are quite minor!
Closes#620

* Tweak the implementation of heap closures
This commit updates the implementation of the `Closure` type to internally store
an `Rc` and be suitable for dropping a `Closure` during the execution of the
closure. This is currently needed for promises but may be generally useful as
well!
* Support asynchronous tests
This commit adds support for executing tests asynchronously. This is modeled
by tests returning a `Future` instead of simply executing inline, and is
signified with `#[wasm_bindgen_test(async)]`.
Support for this is added through a new `wasm-bindgen-futures` crate which is a
binding between the `futures` crate and JS `Promise` objects.
Lots more details can be found in the details of the commit, but one of the end
results is that the `web-sys` tests are now entirely contained in the same test
suite and don't need `npm install` to be run to execute them!
* Review tweaks
* Add some bindings for `Function.call` to `js_sys`
Name them `call0`, `call1`, `call2`, ... for the number of arguments being
passed.
* Use oneshots channels with `JsFuture`
It did indeed clean up the implementation!
In an actual browser, the changing of the history using the binding
worked a little too well, and caused the test to fail if you refreshed
the page or manually used the back and forward buttons. The stateful
stuff has been removed - the remaining two assertions should adequately
test that the binding works, which is the point of these tests anyways.
* Add renaming of conflicting constructors and operations
* Rename conflicting to overloaded
* Fix newlines
* Use or_insert_with, add a comment to TypeToString
* Use more Rust-like names
* Use opt instead of nullable
* Use argument names instead of argument types if possible
* Drop new for overloaded constructots
* Remove extra newline
* Move WebIDL files from unavailable_overloaded_fn
* Move RTCDataChannel, RTCPeerConnection and Selection to unavailable_option_primitive
* Try to enable all webidls
* Separate out unavailable webidl files by reason.
* Create record of fully tested WebIDL files
* Update notes to reflect new situation with web-idl
* Make a blank ident fail, disable the necessary widls.
It turns out that all the blank idents came from blank enum variants,
which is allowed in webidl apparently.
* Adding in initial support for all HTML*Element interfaces.
* Fix camelcasing of short HTML interface names
* Disabling span test as breaks on taskcluster
