Crate memx_cdy 

c interface of memx: the fast memory functions like libc memcmp(), memchr(), memmem(), memcpy(), memset()

Features

• Faster os libc and musl libc
• Replace dynamic os libc using LD_PRELOAD

Quick install

1. You can install this into cargo lib path:

cargo build --release
mkdir -p $HOME/.cargo/lib
cp -a target/release/libmemx_cdy.so target/release/libmemx_cdy.a $HOME/.cargo/lib

2. You can build debian package:

cargo deb

and install .deb into your local repository of debian package.

Usage

Easy to use, LD_PRELOAD.

1. usecase: cargo install

$ LD_PRELOAD=~/.cargo/lib/libmemx_cdy.so command

or

$ export LD_PRELOAD=~/.cargo/lib/libmemx_cdy.so

2. usecase: debian package

$ LD_PRELOAD=/usr/lib/libmemx_cdy.so.0.1 command

or

$ export LD_PRELOAD=/usr/lib/libmemx_cdy.so.0.1

2-step of using on your rust source code

1. add to dependences of Cargo.toml:

[dependencies]
memx-cdy = "0.1"

2. call memx_init() in main function

fn main() {
    memx_cdy::memx_init();
    //
    // follow your code
}

Functions

bcmp

memchr

memcmp

memmem

memrchr

memset

memx_init

This is the dummy function fot the easy linking.
