Trait Implementations

impl Clone for PreviousViewData

fn clone(&self) -> PreviousViewData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for PreviousViewData

where PreviousViewData: 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 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_replace() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_replace 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 CreateFrom for PreviousViewData

where PreviousViewData: ShaderType<ExtraMetadata = StructMetadata<5>>, Mat4: for<'__> CreateFrom + for<'__> CreateFrom + for<'__> CreateFrom + for<'__> CreateFrom + for<'__> CreateFrom,

fn create_from<B>(reader: &mut Reader<B>) -> PreviousViewData

where B: BufferRef,

impl ReadFrom for PreviousViewData

where PreviousViewData: ShaderType<ExtraMetadata = StructMetadata<5>>, Mat4: for<'__> ReadFrom + for<'__> ReadFrom + for<'__> ReadFrom + for<'__> ReadFrom + for<'__> ReadFrom,

fn read_from<B>(&mut self, reader: &mut Reader<B>)

where B: BufferRef,

impl ShaderSize for PreviousViewData

where Mat4: ShaderSize,

const SHADER_SIZE: NonZero<u64> = _

Represents WGSL Size (equivalent to ShaderType::min_size)

impl ShaderType for PreviousViewData

where Mat4: ShaderType + ShaderSize,

fn size(&self) -> NonZero<u64>

Returns the size of Self at runtime

fn min_size() -> NonZero<u64>

Represents the minimum size of Self (equivalent to GPUBufferBindingLayout.minBindingSize)

fn assert_uniform_compat()

Asserts that Self meets the requirements of the uniform address space restrictions on stored values and the uniform address space layout constraints

impl WriteInto for PreviousViewData

where PreviousViewData: ShaderType<ExtraMetadata = StructMetadata<5>>, Mat4: for<'__> WriteInto + for<'__> WriteInto + for<'__> WriteInto + for<'__> WriteInto + for<'__> WriteInto,

fn write_into<B>(&self, writer: &mut Writer<B>)

where B: BufferMut,
