Struct DropAccept 

pub struct DropAccept {
    pub kinds: Vec<MimeKind>,
    pub effects: DropEffectSet,
}

MIME-type filter declared on a [lumen_core::DropTarget] (extended by this crate). Drops are rejected when none of the configured kinds match the source payload.

Authored separately from the marker component so the existing lumen-core::DropTarget stays untouched; entities can carry both.

Fields

kinds: Vec<MimeKind>

MIME kinds this target accepts. Empty means “accept any”.

effects: DropEffectSet

Effects this target advertises. Empty (NONE) rejects.

Implementations

impl DropAccept

pub fn any() -> Self

Accept any MIME - semantics today’s DropTarget already has.

pub fn only(kinds: impl IntoIterator<Item = MimeKind>) -> Self

Accept only the given MIME kinds.

pub fn with_effects(self, effects: DropEffectSet) -> Self

Builder: set the allowed effects.

pub fn accepts_kinds<'a>( &self, kinds: impl IntoIterator<Item = &'a MimeKind>, ) -> bool

True when this accept-set permits a drag advertising kinds.

A hovering drag exposes the kinds it carries before it exposes the payload itself (HTML5 DataTransfer.types during dragenter), which is what lets a target answer “would this drop be taken” while the pointer is still moving. DropAccept::accepts is the same question asked of a payload that has arrived.

pub fn accepts(&self, payload: &MimePayload) -> bool

True when this accept-set permits the supplied payload.

Trait Implementations

impl Clone for DropAccept

fn clone(&self) -> DropAccept

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for DropAccept

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 DropAccept

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

Formats the value using the given formatter.

impl Default for DropAccept

fn default() -> DropAccept

Returns the “default value” for a type.
