After a module goes through its primary GC pass we need to look over the
set of remaining imports and use that to prune the set of imports that
we're binding.
Closes#1613
Recent refactorings of wasm-bindgen have inserted multiple `gc` passes
executed by walrus. In these passes though the function table was being
removed a bit too aggressively because it's not exported by LLD and it's
only later that we realize we need to export it.
To handle this case we add synthetic and temporary exports of the
function table and these exports are removed just after the GC pass in
question.
Closes#1603
Commit b8afa0abde9da31886a35f867d00a63a9cc69cc8 converted several interfaces
from NoInterfaceObject to mixins. It looks like it missed
HTMLHyperlinkElementUtils: it did update the interfaces that use
HTMLHyperlinkElementUtils (from "implements" to "includes"), but did not mark
HTMLHyperlinkElementUtils as a mixin.
Fix it, which makes HtmlAnchorElement gain useful functions like `set_href`.
Commit 8ace8287ff75214fe955bb1819df9e8aa216d325 made the argument to the
generated init() function optional (when the target is "web"), but it is still
marked as required in the generated .d.ts file.
Fix the generated declaration to match the function definition again.
One of the best parts about concurrency in Rust is using `rayon` and how
easy it makes parallelization of tasks, so it's the ideal example for
parallel Rust on the web! Previously we've been unable to use `rayon`
because there wasn't a way to customize how rayon threads themselves are
spawned, but [that's now being developed for us][rayon]!
This commit uses that PR to rewrite the `raytrace-parallel` example in
this repository. While not a perfect idiomatic representation of using
`rayon` I think this is far more idiomatic than the previous iteration
of `raytrace-parallel`! I'm hoping that we can continue to iterate on
this, but otherwise show it off as a good example of parallel Rust on
the web.

Previously a `Function` didn't actually take into account the self
pointer and instead left it as an implicit argument. This instead
ensures that there's a `Descriptor::I32` type inside of a `Function`
description that we have to later skip, and this should not only make
the anyref pass correct for Rust exports but it should also make it more
accurate for future webidl transformations.
While this doesn't currently cause issues in the upcoming webidl
refactor this is actually being asserted and causes verification issues
if the types don't align!
These are basically just mistakes from the original implementation of
this module, but this doesn't actually fix a known bug today.
This is just a bit too general to work with and is pretty funky. Instead
just tweak `Clamped<&[u8]>` to naturally generate a descriptor for
`Ref(Slice(ClampedU8))`, requiring fewer gymnastics when interpreting
descriptors.
Instead of allocating space on the stack and returning a pointer we
should be able to use a single global memory location to communicate
this error payload information. This shouldn't run into any reentrancy
issues since it's only stored just before returning to wasm and it's
always read just after returning from wasm.
This was once required due to flavorful management of the `WeakRef`
proposal but nowadays it's simple enough that we don't need to refactor
it out here.
