PyO3: Rust 💚 Python
summary
Implements a Rust counter that checks whether a character appears at least N times with optional newline and space resets, exposes it to Python as a pyclass with a constructor and a has_count method, and uses PyO3 annotations so no separate glue code is needed. Development uses maturin (maturin develop) and produces CPU-specific wheels with maturin build. Code runs, is memory‑safe, and is significantly faster than a pure Python equivalent while remaining zero‑cost in abstractions.
