Is there a way to restrict the type of a parameter to value types only
(struct)? I know of Any and AnyObject, but I'm missing AnyValue.
How can I achieve something like the following, to make sure that the
parameter is immutable and has copy-on-write feature?
protocol Actor: class {
func send(message: AnyValue)
}
I'm curious why AnyValue is missing. Can someone answer this?
Thanks in advance.
