Struct bevy_trait_query::all::WriteTraits

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

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

Implementations

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

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

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

pub fn iter_mut(&mut self) -> CombinedWriteTraitsIter<'_, Trait>

Returns a mutable iterator over the components implementing Trait for the current entity.

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

pub fn iter_added_mut(&mut self) -> impl Iterator<Item = Mut<'_, Trait>>

Returns a mutable 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_mut(&mut self) -> impl Iterator<Item = Mut<'_, Trait>>

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