Detailed Description

template<typename Key, typename AssetClass>
struct Asset::Record< Key, AssetClass >

Internal storage for one asset entry managed by AssetManager.

A record keeps the stable identity of an asset key while the payload changes over time. Asset::Ref instances hold weak references to records so they stay valid across payload replacement and unload operations until the manager clears the record itself.

Template Parameters

Key	Asset lookup key type.
AssetClass	Asset payload type.
