Struct DebugOverlay 

pub struct DebugOverlay { /* private fields */ }

Tracks frame timing and computes FPS statistics over a rolling window.

Stats are cached and only recomputed every update_interval seconds to avoid impacting frame timing.

Implementations

impl DebugOverlay

pub fn new(update_interval: f32) -> DebugOverlay

Creates a new overlay with the given stats update interval.

The rolling window holds up to 120 frame-time samples.

pub fn update(&mut self, delta_time: f32)

Records a frame and recomputes stats if the update interval has elapsed.

pub fn stats(&self) -> FpsStats

Returns the most recently cached FPS statistics.

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

Enables or disables the overlay.

pub fn is_enabled(&self) -> bool

Returns whether the overlay is enabled.

pub fn set_corner(&mut self, corner: OverlayCorner)

Sets the display corner.

pub fn corner(&self) -> OverlayCorner

Returns the current display corner.

pub fn set_update_interval(&mut self, interval: f32)

Sets the stats update interval in seconds.
