[dependencies]
crc = "0.0.1"
or

Add this to crate root
rust
extern crate crc;
Compute CRC32 ```rust use crc::crc32;
let mut digest = crc32::Digest::new(crc32::IEEE); digest.write(&b"123456789"); println!("{:x}", digest.sum32()); // -> 0xcbf43926 ```
Compute CRC64 ```rust use crc::crc64;
let mut digest = crc64::Digest::new(crc64::ECMA); digest.write(&b"123456789"); println!("{:x}", digest.sum64()); // -> 0x995dc9bbdf1939fa ```
cargo bench with 2.3 GHz Intel Core i7 results ~385MB/s throughput as expected
