Function rs_encode 

Source 
pub fn rs_encode(data: &[u8]) -> Vec<u8> ⓘ
Expand description

RS-encode a single data block (systematic encoding).

§Arguments

  • data: Data bytes of length <= K_DEFAULT (191).

§Returns

A vector of data.len() + PARITY_LEN bytes: the original data followed by 64 parity symbols.

§Panics

Panics if data.len() > K_DEFAULT.

For shortened codes (data.len() < K_DEFAULT), the data is conceptually zero-padded at the front to K_DEFAULT, encoded, then the padding is removed. The parity symbols are computed over this virtual full-length block.
