Struct bevy_trait_query::all::ReadTraits

pub struct ReadTraits<'a, Trait: ?Sized + TraitQuery> { /* private fields */ }

Read-access to all components implementing a trait for a given entity.

Implementations

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

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

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

pub fn iter_added(&self) -> impl Iterator<Item = Ref<'w, Trait>>

Returns an iterator over the components implementing Trait for the current entity that were added since the last time the system was run.

pub fn iter_changed(&self) -> impl Iterator<Item = Ref<'w, Trait>>

Returns an iterator over the components implementing Trait for the current entity whose values were changed since the last time the system was run.

Trait Implementations

impl<'w, Trait: ?Sized + TraitQuery> IntoIterator for &ReadTraits<'w, Trait>

type Item = Ref<'w, Trait>

The type of the elements being iterated over.

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

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
