Enum LayoutStep 

pub enum LayoutStep {
    Intrinsics(Vec<LeafData>),
    Heights(Vec<LeafData>, Vec<HeightRequest>),
    Done(Box<LayoutOutput>),
    Idle,
}

One step of a resumable layout pass (Surface::layout_begin).

Variants

Intrinsics(Vec<LeafData>)

Measure these leaves’ intrinsics; answer with layout_intrinsics.

Heights(Vec<LeafData>, Vec<HeightRequest>)

Measure these heights; answer with layout_heights.

Done(Box<LayoutOutput>)

The pass is complete.

Idle

No pass in progress (an answer without layout_begin).
