Struct ChecksumContextMap

Source

pub struct ChecksumContextMap { /* private fields */ }

Expand description

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§

Source §

impl ChecksumContextMap

Source

pub fn new(byte_size: usize) -> Self

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

Source

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

Get state for hash, checking checksum.

Source

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

Set state for hash with checksum.
