pchickey edited PR #2701 from pch/wiggle_async to main:

Following #2434, wiggle now supports async functions. Users of the wiggle macro can specify which functions should be async with a new async_ section of the settings.

The new integration test of wasmtime-wiggle shows async support working end-to-end: https://github.com/bytecodealliance/wasmtime/pull/2701/files#diff-9b1eee5f3bd355b0c43aa2ec5d647ddcc085d50f81324540cdbbce39ca6de21b

I rewrote a bunch of the doc test to document the new functionality, plus other earlier changes that had been left out: https://github.com/bytecodealliance/wasmtime/blob/1e4cde62ab510f6c5b551ab73203b48bff707635/crates/wiggle/macro/src/lib.rs

During this work I realized that the wiggle::from_witx macro did not need to take the user's so-called ctx type as an argument to the macro. Instead, all code generated by wiggle is generic - it will accept any type which implements the required traits. (Async lifetime issues meant it was easier to make this particular type generic rather than concrete, because lifetime parameters can't be elided in some async fn contexts.) The wasmtime-wiggle integration does still require the user to specify a concrete ctx type.

Over in crates/wasmtime, I added a missing function Linker::instantiate_async, for use with async stores.

Could this parse the async keyword itself to avoid the underscore? (given this is a macro I'd assume we could do whatever syntax we wanted here)
