Implementations

impl HTable

pub fn add(&mut self, from: usize, to: usize, depth: u8)

Increases [from][to] history slot value based on depth.

pub fn punish(&mut self, from: usize, to: usize, depth: u8)

Punishes [from][to] history slot value based on depth.

pub fn get(&self, from: usize, to: usize, max: u8) -> u8

Gets [from][to] history slot value, relative to max.

pub fn age_values(&mut self)

Ages all values in the history table by dividing them by the AGING_DIVISOR.

fn age_value(&self, value: u32) -> u32

Ages a single value by dividing value by the AGING_DIVISOR.

Trait Implementations

impl Default for HTable

fn default() -> Self

Constructs a default instance of HTable by allocating 64 * 64 * mem::size_of::<HTableEntry>() boxed array with zeroed elements.
