Expand description
A trait for sending lifecycle notifications from assets in the asset server.
Required Methods§
sourcefn create_asset(
&self,
id: HandleId,
asset: Box<dyn AssetDynamic>,
version: usize
)
fn create_asset( &self, id: HandleId, asset: Box<dyn AssetDynamic>, version: usize )
Notifies the asset server that a new asset was created.
sourcefn free_asset(&self, id: HandleId)
fn free_asset(&self, id: HandleId)
Notifies the asset server that an asset was freed.
Implementations§
source§impl dyn AssetLifecycle
impl dyn AssetLifecycle
sourcepub fn is<__T: AssetLifecycle>(&self) -> bool
pub fn is<__T: AssetLifecycle>(&self) -> bool
Returns true if the trait object wraps an object of type __T
.
sourcepub fn downcast<__T: AssetLifecycle>(
self: Box<Self>
) -> Result<Box<__T>, Box<Self>>
pub fn downcast<__T: AssetLifecycle>( self: Box<Self> ) -> Result<Box<__T>, Box<Self>>
Returns a boxed object from a boxed trait object if the underlying object is of type
__T
. Returns the original boxed trait if it isn’t.
sourcepub fn downcast_rc<__T: AssetLifecycle>(
self: Rc<Self>
) -> Result<Rc<__T>, Rc<Self>>
pub fn downcast_rc<__T: AssetLifecycle>( self: Rc<Self> ) -> Result<Rc<__T>, Rc<Self>>
Returns an Rc
-ed object from an Rc
-ed trait object if the underlying object is of
type __T
. Returns the original Rc
-ed trait if it isn’t.
sourcepub fn downcast_ref<__T: AssetLifecycle>(&self) -> Option<&__T>
pub fn downcast_ref<__T: AssetLifecycle>(&self) -> Option<&__T>
Returns a reference to the object within the trait object if it is of type __T
, or
None
if it isn’t.
sourcepub fn downcast_mut<__T: AssetLifecycle>(&mut self) -> Option<&mut __T>
pub fn downcast_mut<__T: AssetLifecycle>(&mut self) -> Option<&mut __T>
Returns a mutable reference to the object within the trait object if it is of type
__T
, or None
if it isn’t.
