Module Rpc_parallel.Parallel.State

Use State.get to query whether the current process has been initialized as an rpc parallel master (start_app or init_master_exn has been called). We return a State.t rather than a bool so that you can require evidence at the type level. If you want to certify, as a precondition, for some function that start_app was used, require a State.t as an argument. If you don't need the State.t anymore, just pattern match on it.
