pymemchr-c: C Implementation of memchr Library
— Offering a pure C reimplementation of the Rust-based pymemchr, pymemchr-c delivers high-performance byte and substring search functions to Python with extensive SIMD (SSE2/AVX2/NEON) optimizations and runtime CPU feature detection. Its unique "Packed Pair" substring search algorithm enables the C version to outperform both Python's built-in methods (up to 28x faster) and the original Rust extension (up to 1.5x faster for substring operations), all while removing the need for a Rust toolchain.
