Crate mem_cmp [] [src]

Safe memory comparison between types.

Types found in this crate serve as safe wrappers around memcmp operations.

Usage

This crate is available on crates.io and can be used by adding the following to your project's Cargo.toml:

[dependencies]
mem_cmp = "0.1.2"

and this to your crate root:

extern crate mem_cmp;

Comparing Memory

The MemOrd trait provides convenience around the result of a memcmp call by returning an Ordering.

If the only thing that matters is equality, MemEq is also available.

use mem_cmp::*;

let a = [0u8; 256];
let b = [0u32; 64];
let c = [4u32; 64];

assert!(a.mem_eq(&b));
assert!(a.mem_neq(&c));

// Also works with types of different sizes:
assert!(a.mem_neq(&42));

Structs

MemOrdered

A type that implements comparison traits via MemEq and MemOrd.

Traits

MemEq

Trait for equality comparisons performed over bytes directly.

MemOrd

Trait for values whose bytes can be compared directly.
