Struct BitWriter 

pub struct BitWriter { /* private fields */ }

MSB-first bit writer accumulating into an owned Vec<u8>.

Implementations

impl BitWriter

pub fn new() -> Self

Create an empty writer.

pub fn bit_pos(&self) -> usize

Number of bits written so far.

pub fn byte_aligned(&self) -> bool

True if the next write would start on a byte boundary.

pub fn write_bit(&mut self, bit: u32)

Append a single bit (only bit 0 of bit is used).

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

Write the low n bits of value MSB-first. n must be ≤ 32; bits above bit n-1 of value are ignored.

pub fn write_bits_u64(&mut self, value: u64, n: u32)

Write the low n bits of a u64 MSB-first. n must be ≤ 64.

pub fn write_ue(&mut self, value: u32) -> Result<(), BitstreamError>

Write an unsigned Exp-Golomb (ue(v)) code — the inverse of BitReader::ue. Refuses u32::MAX because code_num = value + 1 would overflow.

pub fn write_se(&mut self, value: i32) -> Result<(), BitstreamError>

Write a signed Exp-Golomb (se(v)) code — the inverse of BitReader::se.

pub fn align_to_byte(&mut self)

Pad with zero bits up to the next byte boundary.

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

Consume the writer and return the accumulated bytes. The final byte’s unused low bits (if the bit count is not a multiple of 8) are zero.

pub fn as_bytes(&self) -> &[u8]

Borrow the accumulated bytes without consuming the writer.

Trait Implementations

impl Clone for BitWriter

fn clone(&self) -> Self

Returns a duplicate of the value.

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.
