Function cai_hamming::decode

pub fn decode<T: PrimInt>(word: T, par: &[T], locs: &[T]) -> Option<(T, usize)>

Decode the given N-bit word to the nearest codeword using the given M×N parity-check matrix and 2^M×N error location lookup table, correcting up to one bit error.

The word should be in systematic form, with k data bits in the MSB followed by N-k parity bits in the LSB.

On success, return Some((word, err)), where word is the decoded N-bit codeword and err is the number of corrected errors. Otherwise, return None if the word was detected to be unrecoverable.
