Rust AST Explorer
Paste in any Rust code. See the AST (Abstract Syntax Tree).
Hopefully useful for anyone creating proc macros.
\[Update: AST explorer is fancier. I saw it, but missed its Rust option, which is via a pull down.\]
Rust makes this project easy by providing the syn crate (parsing and formatting) and WASM (for interactivity). Source code lives at https://github.com/CarlKCarlK/rust-ast-explorer. Contributions welcome.
