Struct FrameSample 

pub struct FrameSample {
    pub input_ms: f32,
    pub view_ms: f32,
    pub layout_ms: f32,
    pub render_ms: f32,
    pub wait_ms: f32,
}

One frame’s cost in milliseconds, split by phase.

Fields

input_ms: f32

Input handling since the previous frame (event routing + edits).

view_ms: f32

Host + extension view() calls (tree building).

layout_ms: f32

Layout, text measurement, and display-list emission.

render_ms: f32

GPU encode + present (actual work).

wait_ms: f32

Blocked waiting for a swapchain image (vsync backpressure) — real latency, but pacing rather than work.

Implementations

impl FrameSample

pub fn total(&self) -> f32

pub fn work(&self) -> f32

Time the app is responsible for (everything except vsync pacing).
