Struct Fps

pub struct Fps { /* private fields */ }

Simple type for tracking frames-per-second.

Implementations

impl Fps

pub const DEFAULT_WINDOW_LEN: usize = 60usize

The window length used by the default constructor.

pub fn with_window_len(window_len: usize) -> Self

Create a new Fps with the given window length as a number of frames.

The larger the window, the “smoother” the FPS.

pub fn tick(&self)

Call this once per frame to allow the Fps instance to sample the rate internally.

pub fn avg(&self) -> f64

Retrieve the average frames-per-second at the moment of the last call to tick.

pub fn min(&self) -> f64

Retrieve the minimum frames-per-second that was reached within the window at the moment tick was last called.

pub fn max(&self) -> f64

Retrieve the maximum frames-per-second that was reached within the window at the moment tick was last called.

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

Performs copy-assignment from source.

impl Debug for Fps

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

Formats the value using the given formatter.

impl Default for Fps

fn default() -> Self

Returns the “default value” for a type.
