Struct BackdropInput 

pub struct BackdropInput(pub FilterChain);

The wire backdropFilter chain of a node, mirrored off the applied style by crate::ui_map::apply_style_masked’s BACKDROP arm — present iff the style carries a non-empty chain. Same contract as FilterInput: the style apply owns writes (the applied style may be hover/press/focus-merged), the resolver only reads.

Trait Implementations

impl ChainInput for BackdropInput

const KIND_UNKNOWN: &'static str = "backdropFilterUnknown"

Diag kind reported for an unknown filter name.

const KIND_PARAMS: &'static str = "backdropFilterParams"

Diag kind reported for rejected params.

const FORCE_ALWAYS_DIRTY: bool = true

Force always_dirty on every resolved chain. Backdrop chains set this: their source (the frame behind the node) is live, so the filter run must re-stage every frame regardless of USES_TIME.

fn chain(&self) -> &FilterChain

impl Clone for BackdropInput

fn clone(&self) -> BackdropInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for BackdropInput

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]

impl Debug for BackdropInput

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

Formats the value using the given formatter.

impl Default for BackdropInput

fn default() -> BackdropInput

Returns the “default value” for a type.

impl PartialEq for BackdropInput

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

Equality operator ==.

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

Inequality operator !=.
