Module prelude

The asset prelude.

This includes the most common types in this crate, re-exported for your convenience.

Structs

• AssetChanged
  Filter that selects entities with an A for an asset that changed after the system last ran, where A is a component that implements AsAssetId.
• AssetPlugin
  Provides “asset” loading and processing functionality. An Asset is a “runtime value” that is loaded from an AssetSource, which can be something like a filesystem, a network, etc.
• AssetServer
  Loads and tracks the state of Asset values from a configured AssetReader. This can be used to kick off new asset loads and retrieve their current load states.
• Assets
  Stores Asset values identified by their AssetId.

Enums

• AssetEvent
  Events that occur for a specific loaded Asset, such as “value changed” events and “dependency” events.
• AssetId
  A unique runtime-only identifier for an Asset. This is cheap to Copy/Clone and is not directly tied to the lifetime of the Asset. This means it can point to an Asset that no longer exists.
• AssetMode
  Controls whether or not assets are pre-processed before being loaded.
• Handle
  A handle to a specific Asset of type A. Handles act as abstract “references” to assets, whose data are stored in the Assets<A> resource, avoiding the need to store multiple copies of the same data.
• UntypedHandle
  An untyped variant of Handle, which internally stores the Asset type information at runtime as a TypeId instead of encoding it in the compile-time type. This allows handles across Asset types to be stored together and compared.

Traits

• Asset
  Declares that this type is an asset, which can be loaded and managed by the AssetServer and stored in Assets collections.
• AssetApp
  Adds asset-related builder methods to App.
• DirectAssetAccessExt
  An extension trait for methods for working with assets directly from a World.
