Struct FrameHistogram 

pub struct FrameHistogram { /* private fields */ }

Rolling histogram of the last HISTOGRAM_SIZE frame durations (in µs).

Implementations

impl FrameHistogram

pub fn push(&mut self, duration_us: u64)

Push a new frame duration (in microseconds).

pub fn len(&self) -> usize

Number of samples currently held.

pub fn is_empty(&self) -> bool

Return true if no samples have been recorded yet.

pub fn mean_us(&self) -> f64

Mean frame duration in microseconds over the recorded samples.

pub fn min_us(&self) -> u64

Minimum frame duration in the histogram (µs).

pub fn max_us(&self) -> u64

Maximum frame duration in the histogram (µs).

pub fn p99_us(&self) -> u64

Approximate p99 frame duration (µs): the 99th percentile of the sorted samples in the histogram.
