Struct BitVecWriter 

pub struct BitVecWriter { /* private fields */ }

A growable bit-level writer backed by a Vec<u8>.

Implementations

impl BitVecWriter

pub fn new() -> Self

Creates a new empty BitVecWriter.

pub fn with_capacity(bytes: usize) -> Self

Creates a new BitVecWriter with pre-allocated capacity.

pub const fn bits_written(&self) -> usize

Returns the number of bits written so far.

pub fn write_bit(&mut self, value: bool)

Writes a single bit.

pub fn write_bits(&mut self, value: u64, bits: u8) -> BitResult<()>

Writes up to 64 bits from an unsigned integer.

pub fn align_to_byte(&mut self)

Pads with zero bits until the next byte boundary.

pub fn write_u8_aligned(&mut self, value: u8) -> BitResult<()>

Writes a byte-aligned u8.

pub fn write_u16_aligned(&mut self, value: u16) -> BitResult<()>

Writes a byte-aligned u16 (little-endian).

pub fn write_u32_aligned(&mut self, value: u32) -> BitResult<()>

Writes a byte-aligned u32 (little-endian).

pub fn write_u64_aligned(&mut self, value: u64) -> BitResult<()>

Writes a byte-aligned u64 (little-endian).

pub fn write_varu32(&mut self, value: u32) -> BitResult<()>

Writes a byte-aligned varint u32.

pub fn write_vars32(&mut self, value: i32) -> BitResult<()>

Writes a byte-aligned zigzag varint i32.

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

Finishes writing and returns the byte buffer.
