Struct assets_manager::UntypedHandle

pub struct UntypedHandle { /* private fields */ }

A untyped handle on an asset.

This is an type-erased version of Handle. As with dyn Any, the underlying type can be queried at runtime.

Implementations

impl UntypedHandle

pub fn read(&self) -> AssetReadGuard<'_, dyn Any + Send + Sync>

Locks the pointed asset for reading.

If T implements NotHotReloaded or if hot-reloading is disabled, no reloading can occur so there is no actual lock. In these cases, calling this function does not involve synchronisation.

Returns a RAII guard which will release the lock once dropped.

pub fn id(&self) -> &SharedString

Returns the id of the asset.

pub fn is<T: 'static>(&self) -> bool

Returns true if the inner type is the same as T.

pub fn downcast_ref<T: Storable>(&self) -> Option<&Handle<T>>

Returns a handle to the asset if it is of type T.

pub fn reload_watcher(&self) -> ReloadWatcher<'_>

Returns a ReloadWatcher that can be used to check whether this asset was reloaded.

See Handle::reload_watcher for details.

pub fn last_reload_id(&self) -> ReloadId

Returns the last ReloadId associated with this asset.

It is only meaningful when compared to other ReloadIds returned by the same handle or to ReloadId::NEVER.

pub fn reloaded_global(&self) -> bool

Returns true if the asset has been reloaded since last call to this method with any handle on this asset.

Note that this method and reload_watcher are totally independant, and the result of the two functions do not depend on whether the other was called.

Trait Implementations
