This is a tiny little Rust app to demonstrate Pratt parsing. For a full explanation, see Bob Nystrom's blog post Pratt Parsers: Expression Parsing Made Easy.

This is a Rust port of Bob Nystrom's bantam. The original bantam is implemented in Java (see: https://github.com/munificent/bantam).

This Rust port can be found on github at https://github.com/jwurzer/bantam-rust.

This Rust version is similar in structure and design to the original Java version. The error handling is done with the panic! macro. If a parsing error happened then an error message is printed and the program is stopped. For recoverable error handing checkout the branch with-error-handling (https://github.com/jwurzer/bantam-rust/tree/with-error-handling) instead of this master branch.
