Struct SceneVisibility 

pub struct SceneVisibility { /* private fields */ }

Per-prop scene visibility pairs, flattened so a per-frame refresh during a fade reuses its buffers instead of allocating a slot list per prop: prop i’s draw slots are the spans[i] range of draws, its scene is scenes[i] (None = always visible).

Implementations

impl SceneVisibility

pub fn clear(&mut self)

Forget every prop, retaining the buffers for the next refresh.

pub fn begin_prop(&mut self, scene: Option<AssetId>)

Start the next prop’s entry; its draw slots follow via SceneVisibility::push_draw.

pub fn push_draw(&mut self, draw_idx: usize)

Add one draw slot to the prop most recently begun.

pub fn props(&self) -> impl Iterator<Item = (&[usize], Option<AssetId>)> + '_

Every prop’s (draw slots, scene), in insertion order.

Trait Implementations

impl Default for SceneVisibility

fn default() -> SceneVisibility

Returns the “default value” for a type.
