Enumeration Type Documentation

◆ Kind

enum Kind

top-level distinction of different Kinds of Assets.

For convenience, this classification is slightly denormalised, as AUDIO, and VIDEO are both asset::Media objects, EFFECT and CODEC are asset::Proc objects, while STRUCT and META refer directly to the corresponding Interfaces asset::Struct and asset::Meta.
