Expand description

This trait factors out functions for iterating with bitset over component store. Separated from impl ComponentStore for usage in generic trait types that must be able to create ComponentBitsetIterator and related types.

Automatically implemented for ComponentStore.

Required Methods§

fn get_single_with_bitset( &self, bitset: Rc<BitSetVec>, ) -> Result<&T, QuerySingleError>

Gets an immutable reference to the component if there is exactly one instance of it.

fn get_single_mut_with_bitset( &mut self, bitset: Rc<BitSetVec>, ) -> Result<&mut T, QuerySingleError>

Gets a mutable reference to the component if there is exactly one instance of it.

fn iter_with_bitset( &self, bitset: Rc<BitSetVec>, ) -> Map<UntypedComponentBitsetIterator<'_>, for<'b> fn(_: SchemaRef<'b>) -> &'b T> ⓘ

Iterates immutably over the components of this type where bitset indicates the indices of entities. Slower than iter() but allows joining between multiple component types.

fn iter_with_bitset_optional( &self, bitset: Rc<BitSetVec>, ) -> Map<UntypedComponentOptionalBitsetIterator<'_>, for<'b> fn(_: Option<SchemaRef<'b>>) -> Option<&'b T>> ⓘ

Iterates immutably over the components of this type where bitset indicates the indices of entities. Slower than iter() but allows joining between multiple component types.

fn iter_mut_with_bitset( &mut self, bitset: Rc<BitSetVec>, ) -> Map<UntypedComponentBitsetIteratorMut<'_>, for<'b> fn(_: SchemaRefMut<'b>) -> &'b mut T> ⓘ

Iterates mutable over the components of this type where bitset indicates the indices of entities. Slower than iter() but allows joining between multiple component types.

fn iter_mut_with_bitset_optional( &mut self, bitset: Rc<BitSetVec>, ) -> Map<UntypedComponentOptionalBitsetIteratorMut<'_>, for<'b> fn(_: Option<SchemaRefMut<'b>>) -> Option<&'b mut T>> ⓘ

Iterates mutably over the components of this type where bitset indicates the indices of entities. Slower than iter() but allows joining between multiple component types.

fn bitset(&self) -> &BitSetVec

Get bitset of ComponentStore / implementor.

fn contains(&self, entity: Entity) -> bool

Check whether or not this component store has data for the given entity.

fn component_store(&self) -> &ComponentStore<T>

Get ComponentStore for usage with generic types implementing ComponentIterBitset.
