Struct LayerCaptureRect 

pub struct LayerCaptureRect {
    pub min: Vec2,
    pub size: UVec2,
    pub outset: u32,
}

The layer’s capture rectangle in physical pixels, in the same screen space as UiGlobalTransform — the node’s border box, inflated on every side by the node’s quantized filter outset (blur reads/writes beyond the border box; see crate::filters::quantize_outset). Recomputed every frame after layout by sync_layer_geometry; consumed by extraction. v1 clips the capture to this box (web opacity does not clip — known divergence, diag-warned).

The anchor (min) is fractional and follows the node exactly, so a translation — even subpixel — shifts the capture window and the composite quad by the same amount and never changes the captured pixels (the layer cache holds; the quad is sampled bilinearly at its fractional position). Ancestor clipping cannot break this invariance: captures are clip-independent (see clip) and the ancestor clip clamps the quad at composite time instead. Only size (whole texels, ceil of the border box plus outset) keys texture allocation.

Fields

min: Vec2

Top-left of the capture window (border box minus the outset margin), fractional physical px (may be negative for a partially-offscreen layer — capture is layer-local).

size: UVec2

Capture texture size in whole texels.

outset: u32

The applied quantized outset margin (physical px, per side) — the max of the content and backdrop chains’ outsets. Carried so the render side can recover the un-inflated border box (min + outset .. min + size − outset): the backdrop composite quad must cover only the border box (frost never paints in the outset ring), while its UVs map into the inflated snapshot.

Trait Implementations

impl Clone for LayerCaptureRect

fn clone(&self) -> LayerCaptureRect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for LayerCaptureRect

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = ::bevy::ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns ComponentRelationshipAccessor required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]
