Struct BitWriter 

pub struct BitWriter { /* private fields */ }

Bit-level writer for constructing JPEG-XL bitstreams.

Writes bits in LSB-first order, accumulating a byte buffer.

Implementations

impl BitWriter

pub fn new() -> Self

Create a new empty bit writer.

pub fn with_capacity(bytes: usize) -> Self

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

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

Write up to 32 bits (LSB first).

pub fn write_bool(&mut self, v: bool)

Write a single boolean bit.

pub fn write_u64(&mut self, value: u64)

Write a u64 value using JPEG-XL’s U64 encoding.

pub fn align_to_byte(&mut self)

Align to the next byte boundary by writing zero bits.

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

Consume the writer and return the accumulated byte buffer.

Any partial byte is flushed with zero-padding.

pub fn bytes_written(&self) -> usize

Current number of bytes written (excluding partial byte).

pub fn bits_written(&self) -> usize

Current total bits written.

Trait Implementations

impl Default for BitWriter

fn default() -> Self

Returns the “default value” for a type.
