This module generates exception-raising Client modules from RPC declarations. See the GenClient module for a description of the common entries.

Parameters

Signature

include RPC
  with type implementation = unit
   and type 'a res = rpcfn -> 'a
   and type ('a, 'b) comp = 'a

type implementation = unit

The implementation is dependent on the module, and represents the 'result' of the entire module. For example, in the Server module, the `implementation` is the server function, with type

Rpc.call -> Rpc.response.

For the Client module, the individual declarations are used to perform the RPCs, and the 'implementation' type is simply unit.

val implement : Interface.description -> implementation

To actually construct the implementation, an interface description must be provided

type 'a res = rpcfn -> 'a

'a res is the result type of declaring a function. For example, the Client module, given an (int -> int -> int) fn, will return a function of type 'a - in this case, (int -> int -> int)

type ('a, 'b) comp = 'a

This is for inserting a type in between the function application and its result. For example, this could be an Lwt.t, meaning that the result of a function application is a thread

type _ fn

The GADT specifying the type of the RPC

val (@->) : 'a Param.t -> 'b fn -> ('a -> 'b) fn

This infix operator is for constructing function types

val returning : 'a Param.t -> 'b Error.t -> ('a, 'b) comp fn

This defines the return type of an RPC

val declare : string -> string list -> 'a fn -> 'a res

declare name description typ is how an RPC is declared to the module implementing the functionality. The return type is dependent upon the module being used
