pub trait AssetLifecycle: Downcast + Send + Sync + 'static {
    // Required methods
    fn create_asset(
        &self,
        id: HandleId,
        asset: Box<dyn AssetDynamic>,
        version: usize
    );
    fn free_asset(&self, id: HandleId);
}

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

Required Methods

fn create_asset( &self, id: HandleId, asset: Box<dyn AssetDynamic>, 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

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

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

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.

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.

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.

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.
