Struct Log

pub struct Log { /* private fields */ }

A struct holding information about the previous logging interval

Implementations

impl Log

pub fn delta_time_avg(&self) -> Duration

frame time averaged over the interval since the last call to Timer::log

pub fn delta_time_avg_ms(&self) -> f64

frame time averaged over the interval since the last call to Timer::log in milliseconds
