This is a simple crc32 hash algorithm based on the Go Rosetta Stone implementation found here: https://rosettacode.org/wiki/CRC-32 which has the copyright notice:

#Status

The code has been updated to support compiler:

$ moon version --all

HashFunc

source

pub(open) trait HashFunc {
  name(Self) -> String
  write(Self, Byte) -> Unit
  check_sum(Self) -> String
}

HashFunc represents a hash algorithm like @crc32, @md5, or @sha256.

Digest

source

pub(all) struct Digest {
  crc : UInt
  name : String
}

@crc32.Digest implements the 32-bit cyclic redundancy check, or CRC-32, checksum. See https://en.wikipedia.org/wiki/Cyclic_redundancy_check for information. This package is based on the Go Rosetta Stone implementation found here: https://rosettacode.org/wiki/CRC-32

impl HashFunc for Digest

fn check_sum(self : Digest) -> String

source

check_sum returns the final crc32 as a hex string.

fn name(self : Digest) -> String

source

fn write(self : Digest, b : Byte) -> Unit

source

write writes a byte to the digest.

Digest::digest

source

fn Digest::digest(self : Digest) -> UInt

digest returns the final crc32 as a UInt.

Digest::new

source

fn Digest::new() -> Digest

Digest::new returns a new, reset Digest, ready to sum.
