Crate amethyst_assets

amethyst_assets

Asset management crate. Designed with the following goals in mind:

• Extensibility
• Asynchronous & Parallel using Rayon
• Allow different sources

Macros

register_format	Register a dynamically deserializable format for given asset data type. Note that provided asset data type must also be registered using register_format_type macro.
register_format_type	Register specific asset data types that can be deserialized with dynamic formats. This is very useful for all assets that have any format types explicitly implemented. Registered assets are used during loading of nested assets to determine format type which will be used to deserialize that asset.

Structs

AssetLoaderSystemData	Helper type for loading assets
AssetStorage	An asset storage, storing the actual assets and allocating handles to them.
Cache	A simple cache for asset handles of type A. This stores WeakHandle, so it doesn't keep the assets alive.
Directory	Directory source.
FormatValue	The Ok return value of Format::import for a given asset type A.
Handle	A handle to an asset. This is usually what the user deals with, the actual asset (A) is stored in an AssetStorage.
HotReloadBundle	This bundle activates hot reload for the Loader, adds a HotReloadStrategy and the HotReloadSystem.
HotReloadStrategy	An ECS resource which allows to configure hot reloading.
HotReloadSystem	System for updating HotReloadStrategy.
Loader	The asset loader, holding the sources and a reference to the ThreadPool.
Prefab	Main Prefab structure, containing all data loaded in a single prefab.
PrefabLoader	Helper structure for loading prefabs.
PrefabLoaderSystem	System that load Prefabs for PrefabData T.
Processor	A default implementation for an asset processing system which converts data to assets and maintains the asset storage for A.
ProgressCounter	A progress tracker which is passed to the Loader in order to check how many assets are loaded.
RonFormat	Format for loading from Ron files. Mostly useful for prefabs. This type cannot be used for tagged deserialization. It is meant to be used at top-level loading, manually specified to the loader.
SingleFile	An implementation of Reload which just stores the modification time and the path of the file.
ThreadPool	Represents a user created thread-pool.
WeakHandle	A weak handle, which is useful if you don't directly need the asset like in caches. This way, the asset can still get dropped (if you want that).

Enums

AssetPrefab	Convenience PrefabData for loading assets of type A using Format F.
Completion	Completion status, returned by ProgressCounter::complete.
ProcessingState	Returned by processor systems, describes the loading state of the asset.

Traits

Asset	One of the three core traits of this crate.
Format	A format, providing a conversion from bytes to asset data, which is then in turn accepted by Asset::from_data. Examples for formats are Png, Obj and Wave.
FormatRegisteredData	A trait for all asset types that have their format types. Use this as a bound for asset data types when used inside boxed format types intended for deserialization. registered with register_format_type macro.
PrefabData	Trait for loading a prefabs data for a single entity
ProcessableAsset	Defines a way to process asset's data into the asset. This allows using default Processor system to process assets that implement that type.
Progress	The Progress trait, allowing to track which assets are imported already.
Reload	The Reload trait provides a method which checks if an asset needs to be reloaded.
Source	A trait for asset sources, which provides methods for loading bytes.
Tracker	The Tracker trait which will be used by the loader to report back to Progress.
