Struct bevy::asset::ErasedLoadedAsset

pub struct ErasedLoadedAsset { /* private fields */ }

A “type erased / boxed” counterpart to LoadedAsset. This is used in places where the loaded type is not statically known.

Implementations

impl ErasedLoadedAsset

pub fn take<A>(self) -> Option<A>

where A: Asset,

Cast (and take ownership) of the Asset value of the given type. This will return Some if the stored type matches A and None if it does not.

fn decompress<A: Asset>(
    mut commands: Commands,
    asset_server: Res<AssetServer>,
    mut compressed_assets: ResMut<Assets<GzAsset>>,
    query: Query<(Entity, &Compressed<A>)>,
) {
    for (entity, Compressed { compressed, .. }) in query.iter() {
        let Some(GzAsset { uncompressed }) = compressed_assets.remove(compressed) else {
            continue;
        };

        let uncompressed = uncompressed.take::<A>().unwrap();

        commands
            .entity(entity)
            .remove::<Compressed<A>>()
            .insert(asset_server.add(uncompressed));
    }
}

pub fn get<A>(&self) -> Option<&A>

where A: Asset,

Retrieves a reference to the internal Asset type, if it matches the type A. Otherwise returns None.

pub fn asset_type_id(&self) -> TypeId

Retrieves the TypeId of the stored Asset type.

pub fn asset_type_name(&self) -> &'static str

Retrieves the type_name of the stored Asset type.

pub fn get_labeled( &self, label: impl Into<CowArc<'static, str>> ) -> Option<&ErasedLoadedAsset>

Returns the ErasedLoadedAsset for the given label, if it exists.

pub fn iter_labels(&self) -> impl Iterator<Item = &str>

Iterate over all labels for “labeled assets” in the loaded asset
