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§
Sourcetype Asset: Asset
type Asset: Asset
The top level Asset
loaded by this AssetLoader
.
Sourcetype 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§
Sourcefn load<'a>(
&'a self,
reader: &'a mut Reader<'_>,
settings: &'a Self::Settings,
load_context: &'a mut LoadContext<'_>,
) -> impl ConditionalSendFuture<Output = Result<Self::Asset, Self::Error>>
fn load<'a>( &'a self, reader: &'a mut Reader<'_>, settings: &'a Self::Settings, load_context: &'a mut LoadContext<'_>, ) -> impl ConditionalSendFuture<Output = Result<Self::Asset, Self::Error>>
Asynchronously loads AssetLoader::Asset
(and any other labeled assets) from the bytes provided by Reader
.
Provided Methods§
Sourcefn 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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
Implementations on Foreign Types§
Source§impl AssetLoader for ()
impl AssetLoader for ()
The () loader should never be called. This implementation exists to make the meta format nicer to work with.
