alexcrichton opened PR #2659 from witx-next to main:

This commit updates to the 0.9 version of the witx crate implemented in
WebAssembly/wasi#395. This new version drastically changes code
generation and how we interface with the crate. The intention is to
abstract the code generation aspects and allow code generators to
implement much more low-level instructions to enable more flexible APIs
in the future. Additionally a bunch of *.witx files were updated in
the WASI repository.

It's worth pointing out, however, that wasi-common does not change as
a result of this change. The shape of the APIs that we need to implement
are effectively the same and the only difference is that the shim
functions generated by wiggle are a bit different.

@pchickey do you have thoughts on adding back the to/from abi repr traits? I originally removed them because I figured it was good to trim things down to just the in-memory type to avoid too many conversions being available, but it ended up showing up a good amount in tests.

I'm fine with either - using as in tests is OK with me, or maybe we should do types::Errno::try_from(res).unwrap() on the lhs? If you don't want to provide too many From impls maybe define a FromAbi trait in wiggle that has the same shape, but has docs saying its just for wiggle use?
