Inputs

• wasmtime-version: Which version of Wasmtime to install. This can be an exact version specifier such as 16.0.0 or a semver range like ~16.0.0 or 16.x. Use latest to always install the latest release. Defaults to latest.

• wasmtime-token: The GitHub token to use when fetching the version list from bytecodealliance/wasmtime. You shouldn't have to touch this. The default is the github.token if you're on github.com or unauthenticated (rate limited) if you're not on github.com.

• wasmtime-version: The version of Wasmtime that was installed. This will be something like 16.0.0 or similar.

• cache-hit: Whether or not Wasmtime was restored from the runner's cache or download anew.
