Expand description

Turns one source path into a decoded asset.

Implement it to teach the asset pipeline a format it does not know, then register it with crate::AssetServer::register_loader (or crate::register_asset_loader from a plugin’s build). Loaders run on the decode worker pool, so an implementation must be Send + Sync and should assume it is blocking a thread.

Required Methods§

Source

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

File extensions this loader claims, lowercase and without the dot. Registering a loader claims every extension it names; a later registration wins over an earlier one for the same extension.

Source

fn kind(&self) -> AssetKind

The family this loader produces. The object-safe stand-in for Bevy’s associated type Asset.

Source

fn load(&self, ctx: &LoadContext<'_>) -> Result<LoadedAsset, LoadErrorKind>

Loads one asset. Returning Err caches the failure against the path and attaches a failure component to every entity waiting on it.
