Struct PreparedQuery2 

pub struct PreparedQuery2<A: 'static, B: 'static> { /* private fields */ }

Owner-scoped, reusable two-component query with driver reselection and optional materialization.

Implementations

impl<A: 'static, B: 'static> PreparedQuery2<A, B>

pub fn iter<'w, 'c>( &'w mut self, world: &'w mut World, window: QueryWindow<'c>, ) -> Result<Query2<'w, 'c, A, B>, QueryError>

Read iterator over matches for the chosen QueryWindow.

pub fn for_each_mut_mut( &mut self, world: &mut World, window: QueryWindow<'_>, f: impl FnMut(EntityId, &mut A, &mut B) -> Result<(), QueryError>, ) -> Result<(), QueryError>

Mutable traversal borrowing both components for each match.

pub fn for_each_mut_mut_with_effects( &mut self, world: &mut World, window: QueryWindow<'_>, f: impl FnMut(EntityId, &mut A, &mut B, &mut QueryEffects<'_>) -> Result<(), QueryError>, ) -> Result<(), QueryError>

Mutable traversal over both components with optional QueryEffects.

pub fn for_each_mut_read( &mut self, world: &mut World, window: QueryWindow<'_>, f: impl FnMut(EntityId, &mut A, &B) -> Result<(), QueryError>, ) -> Result<(), QueryError>

Mutable traversal over the first component while borrowing the second immutably.

pub fn for_each_mut_read_with_effects( &mut self, world: &mut World, window: QueryWindow<'_>, f: impl FnMut(EntityId, &mut A, &B, &mut QueryEffects<'_>) -> Result<(), QueryError>, ) -> Result<(), QueryError>

Mixed mut/read traversal with optional QueryEffects.
