Function gen_encode_matrix 

Source 
pub fn gen_encode_matrix<'a, GF: 'a + From<u8> + Into<u8> + GaloisField>(
    k: usize,
    l: usize,
    r: usize,
) -> Result<impl Iterator<Item = u8> + DoubleEndedIterator + FusedIterator + 'a, MatrixGenError>
Expand description

Generate encode matrix for a (k,l,r) Local Reconstruction Code.

The k data symbols divided into l groups with each having a single local parity symbol and r global parity symbols.
