Struct ruzstd::decoding::bit_reader_reverse::BitReaderReversed

pub struct BitReaderReversed<'s> { /* private fields */ }

Zstandard encodes some types of data in a way that the data must be read back to front to decode it properly. BitReaderReversed provides a convenient interface to do that.

Implementations

impl<'s> BitReaderReversed<'s>

pub fn bits_remaining(&self) -> isize

How many bits are left to read by the reader.

pub fn new(source: &'s [u8]) -> BitReaderReversed<'_>

pub fn get_bits(&mut self, n: u8) -> u64

Read n number of bits from the source. Will read at most 56 bits. If there are no more bits to be read from the source zero bits will be returned instead.

pub fn get_bits_triple(&mut self, n1: u8, n2: u8, n3: u8) -> (u64, u64, u64)

Same as calling get_bits three times but slightly more performant

pub fn reset(&mut self, new_source: &'s [u8])
