Expand description

A trait for sending lifecycle notifications from assets in the asset server.

Required Methods§

fn create_asset( &self, id: HandleId, asset: Box<dyn AssetDynamic + 'static, Global>, version: usize )

Notifies the asset server that a new asset was created.

fn free_asset(&self, id: HandleId)

Notifies the asset server that an asset was freed.

Implementations§

§

impl dyn AssetLifecycle + 'static

pub fn is<__T>(&self) -> boolwhere __T: AssetLifecycle,

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T>( self: Box<dyn AssetLifecycle + 'static, Global> ) -> Result<Box<__T, Global>, Box<dyn AssetLifecycle + 'static, Global>>where __T: AssetLifecycle,

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.

pub fn downcast_rc<__T>( self: Rc<dyn AssetLifecycle + 'static> ) -> Result<Rc<__T>, Rc<dyn AssetLifecycle + 'static>>where __T: AssetLifecycle,

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.

pub fn downcast_ref<__T>(&self) -> Option<&__T>where __T: AssetLifecycle,

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>where __T: AssetLifecycle,

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
