dns 6.1.2 · OCaml Package

A map whose keys are record types and their values are the time-to-live and the record set. The relation between key and value type is restricted by the below defined GADT.

module Mx_set : Stdlib.Set.S with type elt = Mx.t

module Txt_set : Stdlib.Set.S with type elt = Txt.t

module Srv_set : Stdlib.Set.S with type elt = Srv.t

module Dnskey_set : Stdlib.Set.S with type elt = Dnskey.t

module Caa_set : Stdlib.Set.S with type elt = Caa.t

module Tlsa_set : Stdlib.Set.S with type elt = Tlsa.t

module Sshfp_set : Stdlib.Set.S with type elt = Sshfp.t

module I : sig ... end

type 'a with_ttl = int32 * 'a

A tuple type whose first component is a time-to-live counter in seconds.

type _ rr =

| Soa : Soa.t rr
| Ns : Domain_name.Host_set.t with_ttl rr
| Mx : Mx_set.t with_ttl rr
| Cname : Cname.t with_ttl rr
| A : Ipaddr.V4.Set.t with_ttl rr
| Aaaa : Ipaddr.V6.Set.t with_ttl rr
| Ptr : Ptr.t with_ttl rr
| Srv : Srv_set.t with_ttl rr
| Dnskey : Dnskey_set.t with_ttl rr
| Caa : Caa_set.t with_ttl rr
| Tlsa : Tlsa_set.t with_ttl rr
| Sshfp : Sshfp_set.t with_ttl rr
| Txt : Txt_set.t with_ttl rr
| Unknown : I.t -> Txt_set.t with_ttl rr
(*
The type of resource record sets, as GADT: the value depends on the specific constructor. There may only be a single SOA and Cname and Ptr record, while other constructors, such as address (A), contain a set of the respective types. The Unknown constructor is used for not specifically supported records. These resource records are usually persisted to disk by a server or resolver. Resource records that are only meant for a single transaction (such as EDNS or TSIG) are not in this GADT, neither is the query type ANY (which answer is computed on the fly), or zone transfer operations (AXFR/IXFR).

val equal_rr : 'a key -> 'a -> 'a -> bool

equal_rr k v v' is true if v = v', false otherwise.

val equalb : b -> b -> bool

equalb b b' is true if the bindings are equal.

type k =

| K : 'a key -> k
(*
The monomorphic type of keys.
*)

val comparek : k -> k -> int

comparek k k' compares k with k' using the defined ordering.

val ppk : k Fmt.t

ppk ppf k pretty-prints k.

val of_int : 
  ?off:int ->
  int ->
  (k, [> `Malformed of int * string ]) Stdlib.result

of_int ~off i constructs a k of the provided integer.

val names : 'a key -> 'a -> Domain_name.Host_set.t

names k v are the referenced domain names in the given binding.

val pp_b : b Fmt.t

pp_b ppf b pretty-prints the binding b.

val text_b : 
  ?origin:'a Domain_name.t ->
  ?default_ttl:int32 ->
  'b Domain_name.t ->
  b ->
  string

text_b ~origin ~default_ttl domain-name binding is the zone file format of binding using domain-name.

val remove_rr : 'a key -> 'a -> 'a -> 'a option

remove_rr k v rem removes rem from v. If the result is an empty set, None is returned.

val union_rr : 'a key -> 'a -> 'a -> 'a

union_rr k l r builds the union of l with r. A potential r Soa or Cname overwrites its l counterpart.

val unionee : 'a key -> 'a -> 'a -> 'a option

unionee k l r unions l with r using union_rr.

val diff : old:t -> t -> t option * t option

diff ~old m computes the difference between old and m. The left projection are the deleted entries, the right projection are the added entries. Soa entries are ignored.

val text : 
  ?origin:'a Domain_name.t ->
  ?default_ttl:int32 ->
  'b Domain_name.t ->
  'c rr ->
  'c ->
  string

text ~origin ~default_ttl name k v is the zone file data for k, v.

val ttl : 'a key -> 'a -> int32

get_ttl k v returns the time-to-live of v.

val with_ttl : 'a key -> 'a -> int32 -> 'a

with_ttl k v ttl updates ttl in v.
