# @std/memchr — SIMD-Accelerated Byte Search for Zeta

Auto-converted from [memchr](https://crates.io/crates/memchr) v2.8.0 via [Dark Factory](https://github.com/murphsicles/dark-factory).

## Features

- **memchr** — find first occurrence of a byte in memory (SIMD on x86_64, aarch64)

- **memrchr** — find last occurrence of a byte

- **memmem** — find first occurrence of a substring (Two-Way algorithm + SIMD)

- **find** — iterator over all occurrences

- **rfind** — reverse iterator over all occurrences

## Performance

Uses SIMD (SSE2, AVX2 on x86_64; NEON on aarch64) for sub-linear byte search performance. Typically 5-10x faster than naive byte-at-a-time scanning.
