Struct moonshine_behavior::BehaviorMutReadOnly

pub struct BehaviorMutReadOnly<B: Behavior> { /* private fields */ }

Automatically generated [WorldQuery] type for a read-only variant of BehaviorMut.

Trait Implementations

impl<B: Behavior> QueryData for BehaviorMutReadOnly<B>

SAFETY: we assert fields are readonly below

type ReadOnly = BehaviorMutReadOnly<B>

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

impl<B: Behavior> WorldQuery for BehaviorMutReadOnly<B>

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> = BehaviorMutReadOnlyItem<'__w, B>

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> = BehaviorMutReadOnlyFetch<'__w, B>

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

type State = BehaviorMutState<B>

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: <BehaviorMutReadOnly<B> as WorldQuery>::Item<'__wlong> ) -> <BehaviorMutReadOnly<B> 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 = _

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) -> BehaviorMutState<B>

Creates and initializes a State for this WorldQuery type.

fn get_state(world: &World) -> Option<BehaviorMutState<B>>

Attempts to initializes a State for this WorldQuery type.

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.
