pub struct BitReader<'a> { /* private fields */ }

Implementations

impl<'a> BitReader<'a>

pub fn new(bytes: &'a [u8]) -> Self

pub fn bits_read(&self) -> usize

pub fn bits_remaining(&self) -> usize

pub fn read_bit(&mut self) -> Result<u8, CodecError>

pub fn read_bits(&mut self, n: u8) -> Result<u32, CodecError>

Read up to 32 bits. Panics are impossible: oversize requests return CodecError::GolombOverflow, underruns return CodecError::EndOfStream.

pub fn skip_bits(&mut self, n: usize) -> Result<(), CodecError>

pub fn read_ue_v(&mut self) -> Result<u32, CodecError>

Exp-Golomb unsigned (ue(v) in the H.26x specs).

Encoding: k leading zero bits, then a 1 bit, then k value bits. The decoded value is (1 << k) - 1 + suffix. Caps the leading zero count at 32 since any code with 33+ leading zeros decodes to a value that does not fit in u32.

pub fn read_se_v(&mut self) -> Result<i32, CodecError>

Exp-Golomb signed (se(v) in the H.26x specs).

Decoded as ue(v) then mapped: 0 -> 0, 1 -> 1, 2 -> -1, 3 -> 2, 4 -> -2, …
