Trait Implementations

impl Clone for View

fn clone(&self) -> View

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for View

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

Formats the value using the given formatter.

impl QueryData for View

SAFETY: we assert fields are readonly below

type ReadOnly = View

The read-only variant of this [QueryData], which satisfies the [ReadOnlyQueryData] trait.

impl WorldQuery for View

unsafe fn set_archetype<'__w>( _fetch: &mut <Self as WorldQuery>::Fetch<'__w>, _state: &Self::State, _archetype: &'__w Archetype, _table: &'__w Table, )

SAFETY: we call set_archetype for each member that implements Fetch

unsafe fn set_table<'__w>( _fetch: &mut <Self as WorldQuery>::Fetch<'__w>, _state: &Self::State, _table: &'__w Table, )

SAFETY: we call set_table for each member that implements Fetch

unsafe fn fetch<'__w>( _fetch: &mut <Self as WorldQuery>::Fetch<'__w>, _entity: Entity, _table_row: TableRow, ) -> <Self as WorldQuery>::Item<'__w>

SAFETY: we call fetch for each member that implements Fetch.

type Item<'__w> = ViewItem<'__w>

The item returned by this [WorldQuery] For QueryData this will be the item returned by the query. For QueryFilter this will be either (), or a bool indicating whether the entity should be included or a tuple of such things.

type Fetch<'__w> = ViewFetch<'__w>

Per archetype/table state used by this [WorldQuery] to fetch Self::Item

type State = ViewState

State used to construct a Self::Fetch. This will be cached inside QueryState, so it is best to move as much data / computation here as possible to reduce the cost of constructing Self::Fetch.

fn shrink<'__wlong: '__wshort, '__wshort>( item: <View as WorldQuery>::Item<'__wlong>, ) -> <View as WorldQuery>::Item<'__wshort>

This function manually implements subtyping for the query items.

unsafe fn init_fetch<'__w>( _world: UnsafeWorldCell<'__w>, state: &Self::State, _last_run: Tick, _this_run: Tick, ) -> <Self as WorldQuery>::Fetch<'__w>

Creates a new instance of this fetch.

const IS_DENSE: bool = true

Returns true if (and only if) every table of every archetype matched by this fetch contains all of the matched components. This is used to select a more efficient “table iterator” for “dense” queries. If this returns true, [WorldQuery::set_table] must be used before [WorldQuery::fetch] can be called for iterators. If this returns false, [WorldQuery::set_archetype] must be used before [WorldQuery::fetch] can be called for iterators.

fn update_component_access( state: &Self::State, _access: &mut FilteredAccess<ComponentId>, )

Adds any component accesses used by this [WorldQuery] to access.

fn init_state(world: &mut World) -> ViewState

Creates and initializes a State for this [WorldQuery] type.

fn get_state(components: &Components) -> Option<ViewState>

Attempts to initialize a State for this [WorldQuery] type using read-only access to [Components].

fn matches_component_set( state: &Self::State, _set_contains_id: &impl Fn(ComponentId) -> bool, ) -> bool

Returns true if this query matches a set of components. Otherwise, returns false.

fn set_access(_state: &mut Self::State, _access: &FilteredAccess<ComponentId>)

Sets available accesses for implementors with dynamic access such as FilteredEntityRef or FilteredEntityMut.
