Struct bevy_ecs::query::QueryParIter

source ·

pub struct QueryParIter<'w, 's, D: QueryData, F: QueryFilter> { /* private fields */ }

Expand description

A parallel iterator over query results of a Query.

This struct is created by the Query::par_iter and Query::par_iter_mut methods.

Implementations§

source §

impl<'w, 's, D: QueryData, F: QueryFilter> QueryParIter<'w, 's, D, F>

source

pub fn batching_strategy(self, strategy: BatchingStrategy) -> Self

Changes the batching strategy used when iterating.

For more information on how this affects the resultant iteration, see BatchingStrategy.

source

pub fn for_each<FN: Fn(QueryItem<'w, D>) + Send + Sync + Clone>(self, func: FN)

Runs func on each query result in parallel.

Panics

If the ComputeTaskPool is not initialized. If using this from a query that is being initialized and run from the ECS scheduler, this should never panic.

source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source §

impl<T> Borrow<T> for T
where T: ?Sized,

source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source §

impl<T> Downcast for T
where T: Any,

source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

source §

impl<T> DowncastSync for T
where T: Any + Send + Sync,

source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
