}Expand description
Provides type-erased access to an AssetLoader.
Required Methods§
fn load<'a>(
&'a self,
reader: &'a mut (dyn AsyncReadAndSeek + Unpin + Sync + Send + '_),
meta: Box<dyn AssetMetaDyn>,
load_context: LoadContext<'a>
) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<ErasedLoadedAsset, Box<dyn Error + Sync + Send>>> + 'a>>
fn load<'a>( &'a self, reader: &'a mut (dyn AsyncReadAndSeek + Unpin + Sync + Send + '_), meta: Box<dyn AssetMetaDyn>, load_context: LoadContext<'a> ) -> Pin<Box<dyn ConditionalSendFuture<Output = Result<ErasedLoadedAsset, Box<dyn Error + Sync + Send>>> + 'a>>
Asynchronously loads the asset(s) from the bytes provided by Reader.
fn extensions(&self) -> &[&str]
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>, DeserializeMetaError>
fn deserialize_meta( &self, meta: &[u8] ) -> Result<Box<dyn AssetMetaDyn>, DeserializeMetaError>
Deserializes metadata from the input meta bytes into the appropriate type (erased as Box<dyn AssetMetaDyn>).
fn default_meta(&self) -> Box<dyn AssetMetaDyn>
fn default_meta(&self) -> Box<dyn AssetMetaDyn>
Returns the default meta value for the AssetLoader (erased as Box<dyn AssetMetaDyn>).
fn type_name(&self) -> &'static str
fn type_name(&self) -> &'static str
Returns the type name of the AssetLoader.
fn type_id(&self) -> TypeId
fn type_id(&self) -> TypeId
Returns the TypeId of the AssetLoader.
fn asset_type_name(&self) -> &'static str
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
fn asset_type_id(&self) -> TypeId
Returns the TypeId of the top-level Asset loaded by the AssetLoader.
