# remoteCall(on:target:invocation:throwing:returning:)

Invoked by the Swift runtime when making a remote call.

## Declaration

```swift
func remoteCall<Act, Err, Res>(on actor: Act, target: RemoteCallTarget, invocation: inout Self.InvocationEncoder, throwing: Err.Type, returning: Res.Type) async throws -> Res where Act : DistributedActor, Err : Error, Self.ActorID == Act.ID
```

## Discussion

Discussion The arguments are the arguments container that was previously created by makeInvocationEncoder and has been populated with all arguments. This method should perform the actual remote function call, and await for its response. Serialization Requirement Implementations of this method must ensure that the Argument type parameter conforms to the types’ SerializationRequirement. Errors This method is allowed to throw because of underlying transport or serialization errors, as well as by re-throwing the error received from the remote callee (if able to).
