Expand description

Provides type-erased access to an AssetLoader.

Required Methods§

fn load<'a>( &'a self, reader: &'a mut (dyn AsyncRead + Sync + Unpin + Send + '_), meta: Box<dyn AssetMetaDyn, Global>, load_context: LoadContext<'a> ) -> Pin<Box<dyn Future<Output = Result<ErasedLoadedAsset, Box<dyn Error + Sync + Send, Global>>> + Send + 'a, Global>>

Asynchronously loads the asset(s) from the bytes provided by Reader.

fn extensions(&self) -> &[&str]

Returns a list of extensions supported by this asset loader, without the preceding dot.

fn deserialize_meta( &self, meta: &[u8] ) -> Result<Box<dyn AssetMetaDyn, Global>, DeserializeMetaError>

Deserializes metadata from the input meta bytes into the appropriate type (erased as Box<dyn AssetMetaDyn>).

fn default_meta(&self) -> Box<dyn AssetMetaDyn, Global>

Returns the default meta value for the AssetLoader (erased as Box<dyn AssetMetaDyn>).

fn type_name(&self) -> &'static str

Returns the type name of the AssetLoader.

fn type_id(&self) -> TypeId

Returns the TypeId of the AssetLoader.

fn asset_type_name(&self) -> &'static str

Returns the type name of the top-level Asset loaded by the AssetLoader.

fn asset_type_id(&self) -> TypeId

Returns the TypeId of the top-level Asset loaded by the AssetLoader.
