Struct BitWriter 

pub struct BitWriter {
    pub buffer: Vec<u8>,
    pub bit_pos: usize,
}

Bit-level writer: packs bits into a Vec<u8>.

Fields

buffer: Vec<u8>

bit_pos: usize

Implementations

impl BitWriter

pub fn new() -> Self

Create a new, empty bit writer.

pub fn with_capacity(bytes: usize) -> Self

Create a new writer with pre-allocated capacity (in bytes).

pub fn write_bits(&mut self, value: u32, num_bits: u8)

Write num_bits least-significant bits of value to the stream, MSB first (big-endian bit order within each code word).

pub fn total_bits(&self) -> usize

Total number of bits written so far.

pub fn finish(self) -> (Vec<u8>, usize)

Consume the writer, returning (byte_buffer, total_bit_count).

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BitWriter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BitWriter

fn default() -> Self

Returns the “default value” for a type.
