Crate 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.

Functions

memchr

This mimics libc::memchr(), same as buf.iter().position(|&x| x == by1).

memchr_dbl

This is same as buf.iter().position(|&x| x == by1 || x == by2).

memchr_qpl

This is same as buf.iter().position(|&x| x == by1 || x == by2 || x == by3 || x == by4).

memchr_tpl

This is same as buf.iter().position(|&x| x == by1 || x == by2 || x == by3).

memcmp

This mimics libc::memcmp(), same as a.cmp(&b).

memcpy

This mimics libc::memcpy(), same as dst = src.

memeq

This mimics libc::bcmp(), same as a == b.

memmem

This mimics libc::memmem(), same as (haystack as &str).find(needle as &str) or haystack.windows(needle.len()).position(|window| window == needle).

memnechr

This is same as buf.iter().position(|&x| x != by1), not included libc.

memnechr_dbl

This is same as buf.iter().position(|&x| x != by1 && x != by2), not included libc.

memnechr_qpl

This is same as buf.iter().position(|&x| x != by1 && x != by2 && x != by3 && x != by4), not included libc.

memnechr_tpl

This is same as buf.iter().position(|&x| x != by1 && x != by2 && x != by3), not included libc.

memrchr

This mimics libc::memrchr(), same as buf.iter().rposition(|&x| x == by1).

memrchr_dbl

This is same as buf.iter().rposition(|&x| x == by1 || x == by2).

memrchr_qpl

This is same as buf.iter().rposition(|&x| x == by1 || x == by2 || x == by3 || x == by4).

memrchr_tpl

This is same as buf.iter().rposition(|&x| x == by1 || x == by2 || x == by3).

memrmem

This mimics libc::memrmem(), same as (haystack as &str).rfind(needle as &str) or haystack.windows(needle.len()).rposition(|window| window == needle).

memrnechr

This is same as buf.iter().rposition(|&x| x != by1), not included libc.

memrnechr_dbl

This is same as buf.iter().rposition(|&x| x != by1 && x != by2), not included libc.

memrnechr_qpl

This is same as buf.iter().rposition(|&x| x != by1 && x != by2 && x != by3 && x != by4), not included libc.

memrnechr_tpl

This is same as buf.iter().rposition(|&x| x != by1 && x != by2 && x != by3), not included libc.

memset

This mimics libc::memset(), same as buf.fill(c).
