Struct ChecksumContextMap 

pub struct ChecksumContextMap { /* private fields */ }

Checksummed context map: 2 bytes per entry (checksum + state).

The checksum byte is derived from the upper bits of the hash. On lookup, if the checksum doesn’t match, the entry is treated as state 0.

Implementations

impl ChecksumContextMap

pub fn new(byte_size: usize) -> Self

Create a checksummed ContextMap. byte_size is the total memory in bytes (must be power of 2).

pub fn get(&self, hash: u32) -> u8

Get state for hash, checking checksum.

pub fn set(&mut self, hash: u32, state: u8)

Set state for hash with checksum.
