Struct FseBitWriter 

pub struct FseBitWriter { /* private fields */ }

Optimized FSE bitstream writer.

Uses a 64-bit buffer for efficient bit packing with minimal flushes.

Implementations

impl FseBitWriter

pub fn new() -> Self

Create a new bit writer with pre-allocated capacity.

pub fn with_capacity(capacity: usize) -> Self

Create a new bit writer with specified capacity.

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

Write bits to the stream.

Uses a 64-bit accumulator to minimize flush operations.

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

Finish the bitstream, adding sentinel bit.

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

Get the accumulated bits without finishing.

pub fn len(&self) -> usize

Get current size in bytes (approximate).

pub fn is_empty(&self) -> bool

Check if the writer is empty.

Trait Implementations

impl Debug for FseBitWriter

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

Formats the value using the given formatter.

impl Default for FseBitWriter

fn default() -> Self

Returns the “default value” for a type.
