Struct FrameSample 

pub struct FrameSample {
    pub update: Duration,
    pub acquire: Duration,
    pub render: Duration,
    pub present: Duration,
    pub quads: usize,
    pub glyphs: usize,
    pub draw_calls: usize,
    pub size: (u32, u32),

    pub work: FrameWork,
    pub render_work: RenderWork,
}

What one frame cost. All durations are time on the CPU: waiting for a busy GPU shows up in Self::acquire and Self::present, not in Self::render.

Fields

update: Duration

Rebuilding, laying out and painting the UI.

acquire: Duration

Waiting for a texture to draw on, which vsync and a busy GPU make longer.

render: Duration

Recording and submitting the GPU’s work.

present: Duration

Handing the texture to the window system.

quads: usize

Quads drawn.

glyphs: usize

Glyphs drawn.

draw_calls: usize

Draw calls issued.

size: (u32, u32)

The drawing surface in physical pixels.

scale: f32

Physical pixels per logical pixel.

work: FrameWork

What the UI runtime did.

render_work: RenderWork

What the renderer did.

Implementations
