Python bindings to rust-yaml

rustyaml

This is an experimental rust-powered python extension to parse YAML using rust's serde_yaml and rust-yaml crates.

Code is heavily inspired by https://github.com/mre/hyperjson/ and https://github.com/samuelcolvin/rtoml.

Develop

1. Install rustup and poetry.

2. poetry install will automatically create the venv, compile the package and install it into the venv via the build script.
