Struct PrefixEncoder 

pub struct PrefixEncoder { /* private fields */ }

An encoder-side prefix code: per-symbol emit patterns + lengths, with the single-symbol (0-bit) special case tracked so emission stays in lock-step with PrefixCode::read_symbol.

Implementations

impl PrefixEncoder

pub fn from_lengths(lengths: &[u8]) -> Self

Builds an encoder from per-symbol lengths.

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

Per-symbol code lengths (one entry per symbol; 0 = unused).

pub fn write_symbol(&self, w: &mut BitWriter, symbol: usize)

Writes symbol to w. A single-symbol code writes nothing (0 bits).

Trait Implementations

impl Clone for PrefixEncoder

fn clone(&self) -> PrefixEncoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrefixEncoder

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

Formats the value using the given formatter.
