Expand description

Loads an Asset from a given byte Reader. This can accept AssetLoader::Settings, which configure how the Asset should be loaded.

Required Associated Types§

type Asset: Asset

The top level Asset loaded by this AssetLoader.

type Settings: Settings + Default + Serialize + for<'a> Deserialize<'a>

The settings type used by this AssetLoader.

type Error: Into<Box<dyn Error + Sync + Send>>

The type of error which could be encountered by this loader.

Required Methods§

fn load<'a>( &'a self, reader: &'a mut (dyn AsyncReadAndSeek + Unpin + Sync + Send + '_), settings: &'a Self::Settings, load_context: &'a mut LoadContext<'_>, ) -> impl ConditionalSendFuture

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

Provided Methods§

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.

Object Safety§

This trait is not object safe.

Implementations on Foreign Types§

§

impl AssetLoader for ()

The () loader should never be called. This implementation exists to make the meta format nicer to work with.

§

type Asset = ()

§

type Settings = ()

§

type Error = Error

§

async fn load<'a>( &'a self, _reader: &'a mut (dyn AsyncReadAndSeek + Unpin + Sync + Send + '_), _settings: &'a <() as AssetLoader>::Settings, _load_context: &'a mut LoadContext<'_>, ) -> Result<<() as AssetLoader>::Asset, <() as AssetLoader>::Error>
