Struct egui::context::ViewportRepaintInfo

struct ViewportRepaintInfo {
    cumulative_pass_nr: u64,
    repaint_delay: Duration,
    outstanding: u8,
    causes: Vec<RepaintCause>,
    prev_causes: Vec<RepaintCause>,
    prev_pass_paint_delay: Duration,
}

Per-viewport state related to repaint scheduling.

Fields

cumulative_pass_nr: u64

Monotonically increasing counter.

repaint_delay: Duration

The duration which the backend will poll for new events before forcing another egui update, even if there’s no new events.

Also used to suppress multiple calls to the repaint callback during the same pass.

This is also returned in crate::ViewportOutput.

outstanding: u8

While positive, keep requesting repaints. Decrement at the start of each pass.

causes: Vec<RepaintCause>

What caused repaints during this pass?

prev_causes: Vec<RepaintCause>

What triggered a repaint the previous pass? (i.e: why are we updating now?)

prev_pass_paint_delay: Duration

What was the output of repaint_delay on the previous pass?

If this was zero, we are repainting as quickly as possible (as far as we know).
