Crate memx

memx minics libc.

This crate is implemented memory functions like libc memcmp(), memchr(), memmem(), memcpy(), memset().

Features

• Rewriting with rust lang.
• minimum support rustc 1.46.0 (04488afe3 2020-08-24)

Todo

• Support the zero overhead trait.
• Support more fast routine on armv7-android
• Support more fast routine on x86_64
• Support #![no_std]

Functions

memchr

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

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 != c), not included libc.

memrchr

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

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 != c), not included libc.

memset

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