This commit enables `[NoInterfaceObject]` annotated interfaces in
`web-sys`. The `NoInterfaceObject` attribute means that there's not
actually a JS class for the object, but all of its properties and such
can still be accessed structually and invoked. This should help provide
more bindings for some more common types on the web!
Note that this builds on recent features to ensure that `dyn_into` and
friends always fail for `NoInterfaceObject` objects because they don't
actually have a class.

This commit implements callback interfaces for WebIDL, the final WebIDL
construct that we were unconditionally ignoring! Callback interfaces are
implemented as dictionaries of callbacks. Single-operation callback interfaces
are also expanded when flattening to accept a `Function` as well, in accordance
with the WebIDL spec.
New features have been added to `web-sys` for all the new callback interface
types. Additionally the `EventTarget.webidl` was tweaked to not have
`EventListener?` as this is required for all functional usage and there's no
need to keep that sort of web browser compat here.
Closes#258
This commit adds further support for the `Global` attribute to not only emit
structural accessors but also emit functions that don't take `&self`. All
methods on a `[Global]` interface will not require `&self` and will call
functions and/or access properties on the global scope.
This should enable things like:
Window::location() // returns `Location`
Window::fetch(...) // invokes the `fetch` function
Closes#659
This commit adds support for generating bindings for dictionaries defined in
WebIDL. Dictionaries are associative arrays which are simply objects in JS with
named keys and some values. In Rust given a dictionary like:
dictionary Foo {
long field;
};
we'll generate a struct like:
pub struct Foo {
obj: js_sys::Object,
}
impl Foo {
pub fn new() -> Foo { /* make a blank object */ }
pub fn field(&mut self, val: i32) -> &mut Self {
// set the field using `js_sys::Reflect`
}
}
// plus a bunch of AsRef, From, and wasm abi impls
At the same time this adds support for partial dictionaries and dictionary
inheritance. All dictionary fields are optional by default and hence only have
builder-style setters, but dictionaries can also have required fields. Required
fields are exposed as arguments to the `new` constructor.
Closes#241
This commit moves the `webidl/tests` folder to a new `crates/webidl-tests` crate
(to have a test-only build script) and ports them to the `#[wasm_bindgen_test]`
attribute, which should hopefully make testing much speedier for execution!
