The bindings generation for a class would accidentally omit the `__wrap`
function if it was only discovered very late in the process that
`__wrap` was needed, after we'd already passed the point where we needed
to have decided that.
This commit moves struct field generation of bindings much earlier in
the binding generation process which should ensure everything is all
hooked up by the time we generate the classes themselves.

The official pathname separator on Windows is `\` instead of `/`, but
we've been unconditionally using `/`. This typically works on Windows
because Cargo's default `OUT_DIR` listing is a normal `C:\...` path
which works with either `/` or `\`. If, however, a user sets
`CARGO_TARGET_DIR` to a UNC-style path like `\\?\C:\...` then `/` is
*not* the same as `\`, but rather `/` is interpreted as part of the file
name (to allow file names with `/` in the name).
Let's bypass all this and just use a build script output env var.
Closes#943
These compiler bugs have now been fixed on nightly, so we just need to
wait for the bug fixes to ride the trains to be available to everyone!
Closes#201
The `wasm-bindgen` crate is effectively the only user of this crate now
that the `wasm-gc` tool has been deprecated. It's also much easier to
keep it in this repository as it's easier to sync changes to
`parity-wasm`. I'd also like to start refactoring out utilities for
managing a `parity_wasm::Module` to share between this crate and the
other CLI support code.
Adding `#[inline]` will typically improve codegen for optimized builds
without LTO (so far the majority in practice) by allowing functions that
otherwise couldn't be inlined across codegen units to get inlined
across codegen units.
Right now `wasm-bindgen` has a lot of functions that are very small and
delegate to other functions, but aren't otherwise candidates for
inlining because they're concrete.
I was poking around in release-mode wasm recently and noticed an
alarming number of functions for tiny pieces of functionality, which
motivates this patch!
This commit employs the strategy described in #908 to apply a
non-breaking change to fix WebIDL to be compatible with all browsers,
including Safari.
The problem here is that `BaseAudioContext` and `AudioScheduledSourceNode`
are not types in Safari, but they are types in Firefox/Chrome. The fix
here was to move the contents of these two interfaces into mixins, and
then include the mixins in all classes which inherit from these two
classes. That should have the same effect as defining the methods
inherently on the original interface.
Additionally a special `[RustDeprecated]` attribute to WebIDL was added
to signify interfaces this has happened to. Currently it's directly
tailored towards this case of "this intermediate class doesn't exist in
all browsers", but we may want to refine and extend the deprecation
message over time.
Although it's possible we could do this as a breaking change to
`web-sys` I'm hoping that we can do this as a non-breaking change for
now and then eventually on the next breaking release batch all these
changes together, deleting the intermediate classes. This is also
hopefully a good trial run for how stable web-sys can be when it's
actually stable!

This import is only used if some features get used and it is way easier to just
quiet the warning when those features aren't used than to try and `cfg` this
import.
This commit does a few things, including:
* Fixing the generated JS of `wasm-bindgen` to allow polyfills to work.
(a minor tweak of the generated JS)
* All examples are updated to include a Webpack-specific polyfill for
these two types to get examples working in Edge.
* A new page has been added to the guide about supported browsers. This
mentions known caveats like IE 11 requiring `wasm2js` as well as
documenting some `TextEncoder` and `TextDecoder` workarounds for Edge.
Closes#895
