Struct CompressionTable 

pub struct CompressionTable<const COMP_N: usize> { /* private fields */ }

Bounded compression table — stores (name-bytes-hash, offset-in-message) pairs as back-references. Hashes (instead of names) so we can run no_alloc.

Implementations

impl<const COMP_N: usize> CompressionTable<COMP_N>

pub const fn new() -> CompressionTable<COMP_N>

Empty compression table.

pub fn lookup(&self, hash: u64) -> Option<u16>

Looks up an offset for a name hash, if known.

pub fn insert(&mut self, hash: u64, offset: u16)

Records a (hash, offset) pair. Silently drops the entry if the table is full (legal — yields a larger but valid message).

Trait Implementations

impl<const COMP_N: usize> Default for CompressionTable<COMP_N>

fn default() -> CompressionTable<COMP_N>

Returns the “default value” for a type.
