Expand description

Implementations§

Source§

impl<T: 'static> PreparedQuery1<T>

Source

pub fn iter<'w, 'c>( &'w mut self, world: &'w mut World, window: QueryWindow<'c>, ) -> Result<Query1<'w, 'c, T>, QueryError>

Read iterator over matches for the chosen QueryWindow.

Source

pub fn for_each_mut( &mut self, world: &mut World, window: QueryWindow<'_>, f: impl FnMut(EntityId, &mut T) -> Result<(), QueryError>, ) -> Result<(), QueryError>

Mutable traversal with callback-scoped borrows over the chosen window.

Source

pub fn for_each_mut_with_effects( &mut self, world: &mut World, window: QueryWindow<'_>, f: impl FnMut(EntityId, &mut T, &mut QueryEffects<'_>) -> Result<(), QueryError>, ) -> Result<(), QueryError>

Mutable traversal that may enqueue commands or emit declared events.
