Python bindings to Rust's persistent (immutable) data structures library.

Why you might care

Provides efficient, immutable collections (maps, sets, stacks, queues) for Python with Rust's performance guarantees and thread-safety. Useful as a drop-in replacement for pyrsistent when you need faster immutable data structures in Python applications or libraries that manage state without mutation.
