* Import Wasmtime support from the `wit-bindgen` repo This commit imports the `wit-bindgen-gen-host-wasmtime-rust` crate from the `wit-bindgen` repository into the upstream Wasmtime repository. I've chosen to not import the full history here since the crate is relatively small and doesn't have a ton of complexity. While the history of the crate is quite long the current iteration of the crate's history is relatively short so there's not a ton of import there anyway. The thinking is that this can now continue to evolve in-tree. * Refactor `wasmtime-component-macro` a bit Make room for a `wit_bindgen` macro to slot in. * Add initial support for a `bindgen` macro * Add tests for `wasmtime::component::bindgen!` * Improve error forgetting `async` feature * Add end-to-end tests for bindgen * Add an audit of `unicase` * Add a license to the test-helpers crate * Add vet entry for `pulldown-cmark` * Update publish script with new crate * Try to fix publish script * Update audits * Update lock file
wiggle
Wiggle is a code generator for the host side of a witx interface. It is
invoked as a Rust procedural macro.
Wiggle is not specialized to any particular WebAssembly runtime. It is usable in at least Wasmtime and Lucet.
Learning more
Read the docs on docs.rs.
There are child crates for integrating with Wasmtime and Lucet.
The wasi-common crate is implemented using Wiggle and the wasmtime-wasi crate integrates wasi-common with the Wasmtime engine.
Andrew Brown wrote a great blog post on using Wiggle with Wasmtime.
