Struct bevy_ecs::query::QueryParIter
source · pub struct QueryParIter<'w, 's, Q: WorldQuery, F: ReadOnlyWorldQuery> { /* 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, Q: WorldQuery, F: ReadOnlyWorldQuery> QueryParIter<'w, 's, Q, F>
impl<'w, 's, Q: WorldQuery, F: ReadOnlyWorldQuery> QueryParIter<'w, 's, Q, F>
sourcepub fn batching_strategy(self, strategy: BatchingStrategy) -> Self
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
.
sourcepub fn for_each<FN: Fn(QueryItem<'w, Q>) + Send + Sync + Clone>(self, func: FN)
pub fn for_each<FN: Fn(QueryItem<'w, Q>) + 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.
sourcepub fn for_each_mut<FN: Fn(QueryItem<'w, Q>) + Send + Sync + Clone>(
self,
func: FN
)
👎Deprecated: use .for_each(...)
instead.
pub fn for_each_mut<FN: Fn(QueryItem<'w, Q>) + Send + Sync + Clone>( self, func: FN )
.for_each(...)
instead.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.
