Struct FrameSchedule 

pub struct FrameSchedule {
    pub needs_redraw: bool,
    pub queued_work: bool,
    pub needs_animation_frame: bool,
    pub next_wake_deadline: Option<Instant>,
}

The canonical display-independent frame pipeline.

Both screenshot rendering and FrameHarness input scenarios use this type, so they cannot drift into subtly different sync/layout/draw implementations. Live crate::App additionally owns the window and event loop, but follows the same pass ordering documented by FrameHarness::relayout. Borrowed renderer input plus semantic output from the same real widget frame. Cheap wake demand; deliberately excludes accessibility and inspection trees.

Fields

needs_redraw: bool

A frame drawn now would show something the last one did not: queued work, a changed paint, an animation, a due deadline. False is rest.

queued_work: bool

The part of needs_redraw that is work queued off the tree: a component wake, a pending invocation, a presence change, a layout a row declaration asked for. Widget dirtiness is left out, so a host that takes frames for queued work alone keeps a change drawn by hand (an input the host answers with a frame) from waiting on it.

needs_animation_frame: bool

next_wake_deadline: Option<Instant>

Trait Implementations

impl Clone for FrameSchedule

fn clone(&self) -> FrameSchedule

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FrameSchedule

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for FrameSchedule

fn default() -> FrameSchedule

Returns the “default value” for a type.

impl PartialEq for FrameSchedule

fn eq(&self, other: &FrameSchedule) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
