Continuous integration Coverage Dependencies status Crate Documentation

This is a pure-Rust crate for parsing/formatting Python literals. See the documentation for more information.

This crate is a work-in-progress. The goal is for the parser to support everything ast.literal_eval() does, but it supports only a subset. See the docs for the FromStr implementation for Value for details.
