Enum Score

pub enum Score {
    LowerBound(isize),
    UpperBound(isize),
}

A score in a transposition table.

Variants

LowerBound(isize)

The lower bound of the score. This generally doesn’t bring too much benefit, but still helps optimize a bit.

UpperBound(isize)

The upper bound of the score, which helps get rid of many useless branches.

Trait Implementations

impl Clone for Score

fn clone(&self) -> Score

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Score

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Score

fn eq(&self, other: &Score) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
