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.

The pest.rs domain was previously paid by @dragostis , but it is not a solution that can work in the long term, so we set up a crowdfunding project for the domain registration costs.
