Struct FramePlan 

pub struct FramePlan {
    pub batches: Vec<BackdropBatch>,
}

What one painted frame’s backdrop layers cost.

batches[i] runs after segment i and before segment i + 1, so a frame with n batches renders n + 1 segments.

Fields

batches: Vec<BackdropBatch>

Implementations

impl FramePlan

pub fn render_passes(&self) -> u32

Scene renders this frame costs. Always at least one.

The number the six-panel anti-regression asserts on: it must be 2 for a page of non-overlapping glass, not one per panel.

pub fn blur_passes(&self) -> u32

Filtered regions produced this frame, across every batch.

Distinct from render_passes and it is worth keeping them apart: batching removes render passes, it does not remove blurs. Six panels in one batch is 2 render passes and still 6 blurs. Removing those is what caching them across frames is for, and this is the number that will have to reach zero on a still frame.

pub fn is_empty(&self) -> bool

Whether the frame has any backdrop-filtered layer at all.
