Required Methods§

source

fn load<'a>( &'a self, reader: &'a mut (dyn AsyncRead + Send + Sync + Unpin + '_), settings: &'a Self::Settings, load_context: &'a mut LoadContext<'_> ) -> Pin<Box<dyn Future<Output = Result<Self::Asset, Self::Error>> + Send + 'a>>

Asynchronously loads AssetLoader::Asset (and any other labeled assets) from the bytes provided by Reader.

Provided Methods§

source

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

Returns a list of extensions supported by this AssetLoader, without the preceding dot. Note that users of this AssetLoader may choose to load files with a non-matching extension.
