Public Member Functions
bool	isValid () const noexcept
	Returns true for any non-null handle, including one that may be stale for a store.

	Converts this handle to true when it is non-null.

Public Attributes

uint32_t	generation = 0
	Store-assigned generation. Zero is reserved for the null/default handle.

Detailed Description

template<typename Tag>
struct Engine::Assets::AssetHandle< Tag >

Stable typed reference into an asset registry store.

Handles are safe to store in scene data and components because they do not point directly at payload memory. Resolve them through their owning store when you need the current path, metadata record, or Asset::Ref. generation lets the store reject a handle after the record at index has been replaced.

isValid() only checks that this is not the null handle. Use the owning store's isValid() when the handle came from serialized data or may outlive a registry reset.
