Struct GpuTimer 

pub struct GpuTimer { /* private fields */ }

High-level GPU timer that manages multiple named timing regions.

Implementations

impl GpuTimer

pub fn new() -> Self

Create a new GPU timer with default configuration.

pub fn with_config(config: GpuTimerConfig) -> Self

Create a new GPU timer with the given configuration.

pub fn begin_region(&mut self, label: &str) -> usize

pub fn end_region(&mut self, index: usize) -> Option<Duration>

End a timing region by index, recording the sample.

pub fn begin_frame(&mut self)

Begin a new frame for the frame timer.

pub fn end_frame(&mut self) -> Option<Duration>

End the current frame.

pub fn stats_for_label(&self, label: &str) -> Option<TimingStats>

Get timing statistics for a specific label.

pub fn frame_stats(&self) -> Option<TimingStats>

Get the frame timer statistics.

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

Get the current FPS.

pub fn is_over_budget(&self) -> bool

Check if the average frame time exceeds the target.

pub fn labels(&self) -> Vec<String>

Return all unique labels that have been recorded.

pub fn sample_count(&self) -> usize

Return the total number of samples recorded.

pub fn current_frame_number(&self) -> u64

Return the current frame number.

pub fn is_enabled(&self) -> bool

Check if timing collection is enabled.

pub fn set_enabled(&mut self, enabled: bool)

Enable or disable timing collection.

pub fn reset(&mut self)

Clear all samples and reset the timer.
