WESL Features

Parsing and Stringification

TranslationUnit implements FromStr. Other syntax nodes also implement FromStr: GlobalDirective, GlobalDeclaration, Statement and Expression.

The syntax tree elements implement Display. The display is always pretty-printed.

# use crate::syntax::TranslationUnit;
let source = "@fragment fn frag_main() -> @location(0) vec4f { return vec4(1); }";
let mut module = TranslationUnit::from_str(source).unwrap();
// modify the module as needed...
println!("{module}");
