memx 0.2.0

memory functions like libc memcmp(), memchr(), memmem(), memcpy(), memset()

memx

memx is a Rust library that provides a set of functions for memory manipulation, similar to the standard C library's <string.h>, but implemented in pure Rust and optimized for performance.

Features

A rich set of memory search, comparison, and manipulation functions.
Optimized implementations for x86 and x86-64 architectures using SSE2 and AVX2.
no_std compatibility for use in embedded systems and other resource-constrained environments.
A full suite of iterators for all search functions, providing an idiomatic Rust interface.
