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.
