Struct bevy::asset::processor::LoadAndSave

pub struct LoadAndSave<L, S>where
    L: AssetLoader,
    S: AssetSaver<Asset = <L as AssetLoader>::Asset>,{ /* private fields */ }

A flexible Process implementation that loads the source Asset using the L AssetLoader, then saves that L asset using the S AssetSaver.

When creating custom processors, it is generally recommended to use the LoadAndSave Process implementation, as it encourages you to write both an AssetLoader capable of loading assets without processing enabled and an AssetSaver that allows you to efficiently process that asset type when that is desirable by users. However you can also implement Process directly if LoadAndSave feels limiting or unnecessary.

This uses LoadAndSaveSettings to configure the processor.

Trait Implementations

impl<L, S> From<S> for LoadAndSave<L, S>where L: AssetLoader, S: AssetSaver<Asset = <L as AssetLoader>::Asset>,

fn from(value: S) -> LoadAndSave<L, S>

Converts to this type from the input type.

impl<Loader, Saver> Process for LoadAndSave<Loader, Saver>where Loader: AssetLoader, Saver: AssetSaver<Asset = <Loader as AssetLoader>::Asset>,

type Settings = LoadAndSaveSettings<<Loader as AssetLoader>::Settings, <Saver as AssetSaver>::Settings>

The configuration / settings used to process the asset. This will be stored in the AssetMeta and is user-configurable per-asset.

type OutputLoader = <Saver as AssetSaver>::OutputLoader

The AssetLoader that will be used to load the final processed asset.

fn process<'a>( &'a self, context: &'a mut ProcessContext<'_>, meta: AssetMeta<(), LoadAndSave<Loader, Saver>>, writer: &'a mut (dyn AsyncWrite + Send + Unpin + Sync + 'static) ) -> Pin<Box<dyn Future<Output = Result<<<LoadAndSave<Loader, Saver> as Process>::OutputLoader as AssetLoader>::Settings, ProcessError>> + Send + 'a>>

Processes the asset stored on context in some way using the settings stored on meta. The results are written to writer. The final written processed asset is loadable using Process::OutputLoader. This load will use the returned AssetLoader::Settings.
