Struct FrameTiming 

pub struct FrameTiming { /* private fields */ }

The measured per-run timing summary: never gated, only recorded.

Percentiles are deliberately absent — p50/p99 need a reservoir or a histogram, which is a real design. Count, minimum, maximum and sum are enough for a first baseline; the growth trigger is the first frame budget that needs negotiating.

Implementations

impl FrameTiming

pub const fn new() -> Self

pub fn record(&mut self, cpu_frame: Nanos, drawn: bool)

Record one frame’s measured CPU cost, and whether it presented.

Presented-versus-skipped lives on the measured side deliberately: its purpose is measurement integrity, not determinism. A dormant window presenting nothing would otherwise “run at 40,000 fps” and silently inflate a frame-time baseline.
