protocol Actor : AnyActorThe Actor protocol generalizes over all actor types. Actor types implicitly conform to this protocol.
Supertypes
protocol AnyActorCommon marker protocol providing a shared “base” for both (local)
Actorand (potentially remote)DistributedActortypes.protocol SendableA type whose values can safely be passed across concurrency domains by copying.
Requirements
var unownedExecutor: UnownedSerialExecutorRetrieve the executor for this actor as an optimized, unowned reference.

func assertIsolated(() -> String, file: StaticString, line: UInt) Performs an executor check in debug builds.
func assumeIsolated<T>((isolated Self) throws -> T, file: StaticString, line: UInt) rethrows -> T A safe way to synchronously assume that the current execution context belongs to the passed in actor.
func preconditionIsolated(() -> String, file: StaticString, line: UInt) Unconditionally if the current task is executing on the serial executor of the passed in
actor, and if not crash the program offering information about the executor mismatch.
