Crate of the Week

I'd like to nominate pest, the elegant parser for CotW.

pest is a general purpose parser written in Rust with a focus on accessibility , correctness , and performance . It uses parsing expression grammars (or PEG) as input, which are similar in spirit to regular expressions, but which offer the enhanced expressivity needed to parse complex languages.

(Disclaimer: I contributed greatly towards the end of the 2.0 development cycle.)

We recently released 2.0 and the website is a cool showcase of what Rust-on-wasm does today; you can actually Try It Online!
