}Expand description
Trait for loading resources asynchronously or from various sources.
Loaders are invoked in chain-of-responsibility order when a resource is requested.
Return true to indicate the request was handled (no further loaders are tried),
or false to continue to the next loader.
Required Methods§
Sourcefn load(
&self,
request: ResourceRequest,
options: ResourceLoadOptions,
cx: &mut ResourceContext<'_>,
) -> bool
fn load( &self, request: ResourceRequest, options: ResourceLoadOptions, cx: &mut ResourceContext<'_>, ) -> bool
Attempt to load a resource.
request describes what to load, while options describes how to load it.
Return true if this loader handled the request, false to try the next loader.
Provided Methods§
Sourcefn status(&self, _path: &str) -> LoadingStatus
fn status(&self, _path: &str) -> LoadingStatus
Query the loading status of a resource path.
Default implementation returns NotLoaded — override to track async loading progress.
