Struct DirectHuff 

pub struct DirectHuff { /* private fields */ }

A Huffman table in “direct lookup” form: peek_bits bits index a table of code_len << 8 | symbol entries (zero for unused codes, which consume no bits and decode to symbol 0, which is how incomplete tables behave).

Implementations

impl DirectHuff

pub fn from_counts(source: &[u8]) -> Result<Self>

Build from a table source: 16 code-length counts followed by the symbols in code order.

pub fn from_direct(peek_bits: u32, direct: Vec<u16>) -> Self

Build from a direct table of 1 << peek_bits entries (code_len << 8 | symbol).

pub fn peek_bits(&self) -> u32
