pub struct HandleComponent<T>where
T: Asset,{
pub handle: AssetHandle<T>,
pub uuid: AssetUUID,
}Expand description
A generic ECS component that associates an entity with a shared asset resource. It holds both a handle to the loaded data and the asset’s unique identifier.
Fields§
§handle: AssetHandle<T>A shared, reference-counted pointer to the asset’s data.
uuid: AssetUUIDThe unique, persistent identifier of the asset.
Trait Implementations§
Source§impl<T> Clone for HandleComponent<T>where
T: Asset,
Manual implementation of Clone.
This is cheap as it only clones the reference-counted pointer and the UUID.
It correctly does NOT require T to be Clone.

T: Asset,
Implement Deref to the inner AssetHandle for ergonomic access to the asset data.
This allows calling methods of T directly on the component (e.g., my_mesh_component.vertex_size()).
