Struct WeakHandle

Source

pub struct WeakHandle<T: Asset> { /* private fields */ }

Expand description

A weak handle that does not prevent the asset from being evicted.

Upgrade to an AssetHandle before accessing the data. If the upgrade returns None the asset has been evicted and must be re-loaded.

Implementations§

impl<T: Asset> WeakHandle<T>

Source

pub fn upgrade(&self) -> Option<AssetHandle<T>>

Try to upgrade to a strong handle.

Returns None if all strong handles have been dropped (asset evicted).

Source

pub fn id(&self) -> AssetId<T>

The typed identifier for this asset.

where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
