actorSystemKey
Key which is required to be set on a Decoder’s userInfo while attempting to init(from:) a DistributedActor. The stored value under this key must conform to DistributedActorSystem.
Declaration
static let actorSystemKey: CodingUserInfoKeyDiscussion
Forgetting to set this key will result in that initializer throwing, because an actor system is required in order to call DistributedActor/resolve(id:using:) using it.
