Add this to your
[dependencies] wat = "1.0"
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)?;
This repository and project also aims to provide low-level parsing support for the WAT and WAST formats. Effectively, if you've got an s-expression lookalike that you'd like to parse, you should be able to parse it!
wat crate does not support this because it strives to provide strong
API-level stability guarantees, but the
wast crate has all the
low-level details and is the implementation of the
wast crate. Be sure to
check out its
README.md for more information.
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.
