Struct Ratio 

pub struct Ratio { /* private fields */ }

A measured rate kept as hit/total so the sample size is never lost behind a bare percentage. hits <= total always: every mutator grows total by at least as much as hits in the same step.

Implementations

impl Ratio

pub const fn zero() -> Self

pub fn hit(&mut self)

pub fn miss(&mut self)

pub fn hits(&self) -> usize

pub fn total(&self) -> usize

pub fn rate(&self) -> Option<f64>
