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 has_rep(&self) -> bool

Return true if the control words contain repetition information

pub fn parse_desc( &self, src: &[u8], max_rep: u16, max_visible_def: u16, ) -> ControlWordDesc

Temporarily parses the control word to inspect its properties but does not append to any buffers

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
