public static record RegistryEntry.Direct<T>(T value) extends Record implements RegistryEntry<T>
A direct registry entry holds the value directly. The value does not have to be registered in a registry. Therefore, they receive no ID or registry key, and they cannot be tagged.

This is most often used in data packs to inline one-time use values directly.
