Implementations

source

impl<'w, Trait: ?Sized + TraitQuery> WriteTraits<'w, Trait>

source

pub fn iter(&self) -> CombinedReadTraitsIter<'_, Trait>

Returns an iterator over the components implementing Trait for the current entity.

Trait Implementations

source

impl<'world, 'local, Trait: ?Sized + TraitQuery> IntoIterator for &'local WriteTraits<'world, Trait>

type Item = &'local Trait

The type of the elements being iterated over.

type IntoIter = Chain<ReadTableTraitsIter<'local, Trait>, ReadSparseTraitsIter<'local, Trait>>

Which kind of iterator are we turning this into?

source

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value. Read more

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> Downcast for Twhere
T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more
