Provides a DNS-enabled Resolver_lwt given a network stack. See Make.

Parameters

module R : Mirage_random.C

module T : Mirage_time_lwt.S

module S : Mirage_stack_lwt.V4

Signature

include Resolver_lwt.S with type t = Resolver_lwt.t

type 'a io = 'a Lwt.t

Abstract type of the cooperative threading library used, normally defined via the IO module type

type t = Resolver_lwt.t

State handle for a running resolver

include Ppx_sexp_conv_lib.Sexpable.S with type t := t

val t_of_sexp : Sexplib0__.Sexp.t -> t

val sexp_of_t : t -> Sexplib0__.Sexp.t

type svc = Resolver.service

Abstract type for a service entry, which maps a URI scheme into a protocol handler and TCP port

val sexp_of_svc : svc -> Ppx_sexp_conv_lib.Sexp.t

val svc_of_sexp : Ppx_sexp_conv_lib.Sexp.t -> svc

type rewrite_fn = svc -> Uri.t -> Conduit.endp io

A rewrite function resolves a service and a URI into a concrete endpoint.

type service_fn = string -> svc option io

A service function maps the string (such as http or ftp) from a URI scheme into a service description that includes enough metadata about the service to subsequently resolve it into an endpoint.

val (++) : service_fn -> service_fn -> service_fn

f ++ g is the composition of the service functions f and g.

val init : 
  ?service:service_fn ->
  ?rewrites:(string * rewrite_fn) list ->
  unit ->
  t

init ?service ?rewrites will initialize the resolver and return a state handler. The service argument should contain the system-specific resolution mechanism for URI schemas.

The rewrites argument can optionally override a subset of the URI domain name with the given rewrite_fn to permit custom resolution rules. For example, a rewrite rule for ".xen" would let the rewrite function resolve hostnames such as "foo.xen" into a shared memory channel for the "foo" virtual machine.

val add_rewrite : host:string -> f:rewrite_fn -> t -> unit

add_rewrite ~host f t will add to the t resolver the f rewrite rule for all the domain names that shortest-prefix match host

val set_service : f:service_fn -> t -> unit

val service : t -> service_fn

service t is the function which is called when trying to resolve a hostname with t.

val resolve_uri : 
  ?rewrites:(string * rewrite_fn) list ->
  uri:Uri.t ->
  t ->
  Conduit.endp io

resolve_uri ?rewrites ~uri t will use t to resolve the uri into a concrete endpoint. Any rewrites that are passed in will be overlayed on the existing rules within the t resolver, but not otherwise modify it.
