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
type Asset: Asset
The top level Asset
loaded by this AssetLoader
.
type Settings: Settings + Default + Serialize + for<'a> Deserialize<'a>
type Settings: Settings + Default + Serialize + for<'a> Deserialize<'a>
The settings type used by this AssetLoader
.
Required Methods§
fn load<'a>(
&'a self,
reader: &'a mut (dyn AsyncReadAndSeek + Unpin + Send + Sync + '_),
settings: &'a Self::Settings,
load_context: &'a mut LoadContext<'_>
) -> impl ConditionalSendFuture
fn load<'a>( &'a self, reader: &'a mut (dyn AsyncReadAndSeek + Unpin + Send + Sync + '_), 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]
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 ()
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 + Send + Sync + '_), _settings: &'a <() as AssetLoader>::Settings, _load_context: &'a mut LoadContext<'_> ) -> Result<<() as AssetLoader>::Asset, <() as AssetLoader>::Error>
fn extensions(&self) -> &[&str]
