# ActorID

The type ID that will be assigned to any distributed actor managed by this actor system.

## Declaration

```swift
associatedtype ActorID : Hashable, Sendable
```

## A note on Codable IDs

A note on Codable IDs If this type is Codable, then any distributed actor using this ActorID as its DistributedActor/ID will gain a synthesized Codable conformance which is implemented by encoding the ID. The decoding counter part of the Codable conformance is implemented by decoding the ID and passing it to the resolve(id:using:) method.
