Trait Implementations

impl<F0, F1, F2> QueryFilter for Or<(F0, F1, F2)>

where F0: QueryFilter, F1: QueryFilter, F2: QueryFilter,

const IS_ARCHETYPAL: bool

Returns true if (and only if) this Filter relies strictly on archetypes to limit which components are accessed by the Query.

unsafe fn filter_fetch( fetch: &mut <Or<(F0, F1, F2)> as WorldQuery>::Fetch<'_>, entity: Entity, table_row: TableRow, ) -> bool

Returns true if the provided Entity and TableRow should be included in the query results. If false, the entity will be skipped.

impl<F0, F1, F2> WorldQuery for Or<(F0, F1, F2)>

where F0: QueryFilter, F1: QueryFilter, F2: QueryFilter,

SAFETY: fetch accesses are a subset of the subqueries’ accesses This is sound because update_component_access adds accesses according to the implementations of all the subqueries. update_component_access replace the filters with a disjunction where every element is a conjunction of the previous filters and the filters of one of the subqueries. This is sound because matches_component_set returns a disjunction of the results of the subqueries’ implementations.

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.

type Fetch<'w> = (OrFetch<'w, F0>, OrFetch<'w, F1>, OrFetch<'w, F2>)

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

type Item<'w> = bool

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 State = (<F0 as WorldQuery>::State, <F1 as WorldQuery>::State, <F2 as WorldQuery>::State)

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>( item: <Or<(F0, F1, F2)> as WorldQuery>::Item<'wlong>, ) -> <Or<(F0, F1, F2)> as WorldQuery>::Item<'wshort>

where 'wlong: 'wshort,

This function manually implements subtyping for the query items.

fn shrink_fetch<'wlong, 'wshort>( fetch: <Or<(F0, F1, F2)> as WorldQuery>::Fetch<'wlong>, ) -> <Or<(F0, F1, F2)> as WorldQuery>::Fetch<'wshort>

where 'wlong: 'wshort,

This function manually implements subtyping for the query fetches.

unsafe fn init_fetch<'w>( world: UnsafeWorldCell<'w>, state: &<Or<(F0, F1, F2)> as WorldQuery>::State, last_run: Tick, this_run: Tick, ) -> <Or<(F0, F1, F2)> as WorldQuery>::Fetch<'w>

Creates a new instance of this fetch.

unsafe fn set_table<'w>( fetch: &mut <Or<(F0, F1, F2)> as WorldQuery>::Fetch<'w>, state: &<Or<(F0, F1, F2)> as WorldQuery>::State, table: &'w Table, )

Adjusts internal state to account for the next Table. This will always be called on tables that match this WorldQuery.

unsafe fn set_archetype<'w>( fetch: &mut <Or<(F0, F1, F2)> as WorldQuery>::Fetch<'w>, state: &<Or<(F0, F1, F2)> as WorldQuery>::State, archetype: &'w Archetype, table: &'w Table, )

Adjusts internal state to account for the next Archetype. This will always be called on archetypes that match this WorldQuery.

unsafe fn fetch<'w>( fetch: &mut <Or<(F0, F1, F2)> as WorldQuery>::Fetch<'w>, _entity: Entity, _table_row: TableRow, ) -> <Or<(F0, F1, F2)> as WorldQuery>::Item<'w>

Fetch Self::Item for either the given entity in the current Table, or for the given entity in the current Archetype. This must always be called after WorldQuery::set_table with a table_row in the range of the current Table or after WorldQuery::set_archetype with a entity in the current archetype.

fn update_component_access( state: &<Or<(F0, F1, F2)> as WorldQuery>::State, access: &mut FilteredAccess<ComponentId>, )

Adds any component accesses used by this WorldQuery to access.

fn init_state(world: &mut World) -> <Or<(F0, F1, F2)> as WorldQuery>::State

Creates and initializes a State for this WorldQuery type.

fn get_state( components: &Components, ) -> Option<<Or<(F0, F1, F2)> as WorldQuery>::State>

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

fn matches_component_set( _state: &<Or<(F0, F1, F2)> as WorldQuery>::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.
