Struct bevy::ecs::query::QueryParIter

pub struct QueryParIter<'w, 's, Q, F>where
    Q: WorldQuery,
    F: ReadOnlyWorldQuery,{ /* private fields */ }

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

impl<'w, 's, Q, F> QueryParIter<'w, 's, Q, F>where Q: WorldQuery, F: ReadOnlyWorldQuery,

pub fn batching_strategy( self, strategy: BatchingStrategy ) -> QueryParIter<'w, 's, Q, F>

Changes the batching strategy used when iterating.

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

pub fn for_each<FN>(self, func: FN)where FN: Fn(<Q as WorldQuery>::Item<'w>) + Send + Sync + Clone,

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.

pub fn for_each_mut<FN>(self, func: FN)where FN: Fn(<Q as WorldQuery>::Item<'w>) + Send + Sync + Clone,

👎Deprecated: use .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.
