Implementation

The wrapper is built using PyO3 to interface Rust to Python. This requires (for the moment) unfortunately a bit of overhead code so there exist four layers of code:

• The original Rust library that actually provides all the functionality. Any true code should be placed here as this is shared by all interfaces.

• The PyO3 wrapper objects written in Rust that define which methods are exposed to Python and that takes care of the type conversion from Python-understandable types to Rust types.

• The PyO3 wrapper objects in Python which are an exact mirror of their Rust equivalent. This translation is provided by PyO3 and note that it also preserves the associated documentation.

• The additional Python wrappers around the raw PyO3 objects which provide convenience wrappers to cast arbitrary Python objects to objects that can actually used by PyO3.
