Implementations

impl ControlWordParser

pub fn bytes_per_word(&self) -> usize

Returns the number of bytes per control word

pub fn parse(&self, src: &[u8], dst_rep: &mut Vec<u16>, dst_def: &mut Vec<u16>)

Appends the next control word to the rep & def buffers

src should be pointing at the first byte (little endian) of the control word

dst_rep and dst_def are the buffers to append the rep and def levels to. They will not be appended to if not needed.

pub fn new(bits_rep: u8, bits_def: u8) -> Self

Creates a new parser from the number of bits used for the repetition and definition levels
