wat to your
$ cargo add wat
And then you can parse WAT to binary WebAssembly via:
// Parse from a file ... let binary = wat::parse_file("./foo.wat")?; // ... or a string let wat = r#" (module (func $foo) (func (export "bar") call $foo ) ) "#; let binary = wat::parse_str(wat)?;
wat crate does not expose an AST as its goal is to provide a
forever-stable interface against the
wast crate. Using
wat is suitable when
all you want to do is translate from text-to-binary, for example parsing the
input of a CLI program into the WebAssembly binary format.
If instead you're interested in working with the AST of a text file or otherwise
adding your own parsing to the text format you'll want to take a look at the
Stability and WebAssembly Features
Consult the crate documentation for more information, but the general idea is this crate will not issue a semver-breaking change for breaking changes in the WAT format, either for MVP features or post-MVP features. No opt-in is required to use WebAssembly features, so using them may break if the upstream spec changes.
