Rust crate for parsing/formatting Python literals

py_literal

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.

py_literal's Issues

This crate fails to produce reproducible artifacts

I haven’t investigated too closely what exactly is it, but every time this crate is built in a controlled environment, the produced rlib is wildly different.

I suspect it might be due to pest, but I haven’t investigated too deeply yet.
