In commit 33c791e1f5 (PR #2944), I added LICENSE files to all published
crates. However, since then PR #2897 has been merged and remove 3 crates,
resulting in license files in empty directories.
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.
