CRC Any

Build Status Build status

To compute CRC values by providing the length of bits, expression, reflection, an initial value and a final xor value. It has many built-in CRC functions.

Usage

You can use create_crc associated function to create a CRC instance by providing the length of bits, expression, reflection, an initial value and a final xor value. For example, if you want to compute a CRC-24 value.

extern crate crc_any;

use crc_any::CRC;

let mut crc24 = CRC::create_crc(0x0000000000864CFB, 24, 0x0000000000B704CE, 0x0000000000000000, false);

crc24.digest(b"hello");

assert_eq!([71, 245, 138].to_vec(), crc24.get_crc_vec_be());
assert_eq!("0x47F58A", &crc24.to_string());

To simplify the usage, there are several common versions of CRC whose computing functions are already built-in.

  • crc3gsm
  • crc4itu
  • crc4interlaken
  • crc5epc
  • crc5itu
  • crc5usb
  • crc6cdma2000_a

  • crc24flexray_b
  • crc24lte_a
  • crc24lte_b
  • crc24os9
  • crc30cdma
  • crc32
    • It also called crc32b in mhash.
  • crc32mhash
    • mhash is a common library which has two weird versions of CRC32 called crc32 and crc32b. crc32 and crc32mhash in this module are crc32b and crc32 in mhash respectively.
  • crc32bzip2
  • crc32c
  • crc32d
  • crc32mpeg2
  • crc32posix
  • crc32q
  • crc32jamcrc
  • crc32xfer
  • crc40gsm
  • crc64
  • crc64iso
  • crc64jones

For instance,

extern crate crc_any;

use crc_any::CRC;

let mut crc64 = CRC::crc64();

crc64.digest(b"hello");

assert_eq!([236, 83, 136, 71, 154, 124, 145, 63].to_vec(), crc64.get_crc_vec_be());
assert_eq!("0xEC5388479A7C913F", &crc64.to_string());

After getting a CRC value, you can still use the digest method to continue computing the next CRC values.
