Structure Flat​Map 

public struct FlatMap<Parent: SingleEndpoint, Child: Endpoint>

A struct defining a custom endpoint implementation handling a request generated by the response of a previous one.

This is only available for SingleEndpoint Parents cause we want to be sure to guarantee a deterministic ordering for outputs which is choerent with user expectations (i.e. work like Combine), and it wouldn't otherwise be possible by extending it to LoopEndpoints.
