##Usage Add crc to Cargo.toml

[dependencies]
crc = "0.0.1"

or

[dependencies.crc]
git = "https://github.com/mrhooray/crc"

Add this to crate root

extern crate crc;

Compute CRC32

use crc::crc32;

let mut digest = crc32::Digest::new(crc32::IEEE);
digest.write(&b"123456789");
println!("{:x}", digest.sum32()); // -> 0xcbf43926

Compute CRC64

use crc::crc64;

let mut digest = crc64::Digest::new(crc64::ECMA);
digest.write(&b"123456789");
println!("{:x}", digest.sum64()); // -> 0x995dc9bbdf1939fa
