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.

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.

  • 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.

To compile without any allocation requirement, and no dependency on "debug-helper", disable default features

In Cargo.toml

[dependencies.crc-any]
version = "^2.1.3"
default-features = false
