Struct DlcPackLoader 

pub struct DlcPackLoader {
    pub registrars: Vec<Box<dyn ErasedSubAssetRegistrar>>,
    /* private fields */
}

AssetLoader for .dlcpack bundles (contains multiple encrypted entries).

When the encrypt key is available in the registry at load time (i.e. the DLC is already unlocked), each entry is immediately decrypted and registered as a typed labeled sub-asset so asset_server.load("pack.dlcpack#entry.png") returns the correct Handle<T> for the extension’s loader (e.g. Handle<Image> for .png). No asset type is hardcoded here — the correct type is determined purely by extension dispatch via Bevy’s immediate() loader, and the result is downcast + registered using the list of ErasedSubAssetRegistrars that DlcPlugin::build populates.

When the encrypt key is not yet available the pack is still loaded successfully (entries list is populated from the manifest) but the labeled sub-assets are not added — reload_assets_on_unlock_system will reload the pack once the key arrives, and the second load will succeed.

Fields

registrars: Vec<Box<dyn ErasedSubAssetRegistrar>>

Ordered list of per-type registrars. DlcPlugin::build pushes one TypedSubAssetRegistrar<A> for every A it also registers via init_asset_loader::<DlcLoader<A>>(). The loader tries each in turn and uses the first successful downcast.

Trait Implementations

impl AssetLoader for DlcPackLoader

type Asset = DlcPack

The top level Asset loaded by this AssetLoader.

type Settings = ()

The settings type used by this AssetLoader.

type Error = DlcLoaderError

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

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.

async fn load( &self, reader: &mut dyn Reader, _settings: &Self::Settings, load_context: &mut LoadContext<'_>, ) -> Result<Self::Asset, Self::Error>

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

impl Default for DlcPackLoader

fn default() -> DlcPackLoader

Returns the “default value” for a type.

impl TypePath for DlcPackLoader

fn type_path() -> &'static str

Returns the fully qualified path of the underlying type.

fn short_type_path() -> &'static str

Returns a short, pretty-print enabled path to the type.

fn type_ident() -> Option<&'static str>

Returns the name of the type, or None if it is anonymous.

fn crate_name() -> Option<&'static str>

Returns the name of the crate the type is in, or None if it is anonymous.

fn module_path() -> Option<&'static str>

Returns the path to the module the type is in, or None if it is anonymous.
