Module `Versioned_rpc.Menu`

Over-the-network discovery of rpc names and versions supported by a callee.

This is used by the dispatch_multi functions in Caller_converts and Both_convert to dynamically determine the most appropriate version to use.

type t: A directory of supported rpc names and versions.

val add : 's Rpc.Implementation.t list -> 's Rpc.Implementation.t list: add impls extends a list of rpc implementations with an additional rpc implementation for providing a Menu.t when one is requested via Menu.request.

val implement_multi : ?⁠log_not_previously_seen_version:(name:string -> int -> unit) -> ('s -> version:int -> unit -> Rpc.Description.t list Async_kernel.Deferred.t) -> 's Rpc.Implementation.t list: Specifies directly how to handle the version menu rpc.

val request : Rpc.Connection.t -> t Core_kernel.Or_error.t Async_kernel.Deferred.t: Requests an rpc version menu from an rpc connection.

val supported_rpcs : t -> Rpc.Description.t list: Finds what rpcs are supported.

val supported_versions : t -> rpc_name:string -> Core_kernel.Int.Set.t: Finds what versions of a particular rpc are supported.

val create : Rpc.Description.t list -> t: Creates a menu directly -- generally you should use request instead.

val rpc_name : string: The internal name of this RPC -- for example to be used in Rpc.Expert to distinguish it from other queries.
