pub struct EntityEntryCommands<'a, T> { /* private fields */ }Expand description
A wrapper around EntityCommands with convenience methods for working with a specified component type.
Implementations§
source§impl<'a, T> EntityEntryCommands<'a, T>where
T: Component,
impl<'a, T> EntityEntryCommands<'a, T>where
T: Component,
sourcepub fn and_modify(
&mut self,
modify: impl FnOnce(Mut<'_, T>) + Send + Sync + 'static,
) -> &mut EntityEntryCommands<'a, T>
pub fn and_modify( &mut self, modify: impl FnOnce(Mut<'_, T>) + Send + Sync + 'static, ) -> &mut EntityEntryCommands<'a, T>
Modify the component T if it exists, using the function modify.
sourcepub fn or_insert(&mut self, default: T) -> &mut EntityEntryCommands<'a, T>
pub fn or_insert(&mut self, default: T) -> &mut EntityEntryCommands<'a, T>
Insert default into this entity, if T is not already present.
See also or_insert_with.
§Panics
Panics if the entity does not exist.
See or_try_insert for a non-panicking version.
sourcepub fn or_try_insert(&mut self, default: T) -> &mut EntityEntryCommands<'a, T>
pub fn or_try_insert(&mut self, default: T) -> &mut EntityEntryCommands<'a, T>
Insert default into this entity, if T is not already present.
Unlike or_insert, this will not panic if the entity does not exist.
See also or_insert_with.
sourcepub fn or_insert_with(
&mut self,
default: impl Fn() -> T,
) -> &mut EntityEntryCommands<'a, T>
pub fn or_insert_with( &mut self, default: impl Fn() -> T, ) -> &mut EntityEntryCommands<'a, T>
Insert the value returned from default into this entity, if T is not already present.
See also or_insert and or_try_insert.
§Panics
Panics if the entity does not exist.
See or_try_insert_with for a non-panicking version.
sourcepub fn or_try_insert_with(
&mut self,
default: impl Fn() -> T,
) -> &mut EntityEntryCommands<'a, T>
pub fn or_try_insert_with( &mut self, default: impl Fn() -> T, ) -> &mut EntityEntryCommands<'a, T>
Insert the value returned from default into this entity, if T is not already present.
Unlike or_insert_with, this will not panic if the entity does not exist.
See also or_insert and or_try_insert.
sourcepub fn or_default(&mut self) -> &mut EntityEntryCommands<'a, T>where
T: Default,
pub fn or_default(&mut self) -> &mut EntityEntryCommands<'a, T>where
T: Default,
Insert T::default into this entity, if T is not already present.
See also or_insert and or_from_world.
§Panics
Panics if the entity does not exist.
sourcepub fn or_from_world(&mut self) -> &mut EntityEntryCommands<'a, T>where
T: FromWorld,
pub fn or_from_world(&mut self) -> &mut EntityEntryCommands<'a, T>where
T: FromWorld,
Insert T::from_world into this entity, if T is not already present.
See also or_insert and or_default.
§Panics
Panics if the entity does not exist.
