pymemchr
— pymemchr is a Python library that provides ultra-fast byte and substring search functions by binding to the memchr Rust crate, leveraging SIMD optimizations for superior performance. Using PyO3 and Maturin for cross-language integration, pymemchr offers efficient routines for finding single bytes, searching for multiple bytes, and locating substring patterns, both forwards and backwards, with highly competitive speedup over native Python methods.
