Struct FPSMonitor 

pub struct FPSMonitor { /* private fields */ }

Tracks the timestamps of the last window_size calls to FPSMonitor::tick and estimates current throughput from them.

Implementations

impl FPSMonitor

pub fn new() -> Self

Creates a monitor with the default 30-frame window.

pub fn with_window_size(window_size: usize) -> Self

Creates a monitor averaging over the last window_size ticks.

Panics

Panics if window_size is 0.

pub fn tick(&mut self)

Records that a frame was just processed.

pub fn fps(&self) -> f32

Estimated frames per second, averaged over the current window.

Returns 0.0 until at least two ticks have been recorded (a single timestamp has no elapsed interval to divide by).

pub fn reset(&mut self)

Discards all recorded timestamps, restarting the average.
