val disconnect : t -> unit Lwt.t
type ipaddr = Ipaddr.V4.t

The type for IP addresses.

type error

The type for ICMP errors.

val pp_error : error Fmt.t

pp_error is the pretty-printer for errors.

val input : t -> src:ipaddr -> dst:ipaddr -> Cstruct.t -> unit Lwt.t

input t src dst buffer reacts to the ICMP message in buffer.

val write : t -> ?src:ipaddr -> dst:ipaddr -> ?ttl:int -> Cstruct.t -> (unit, error) Stdlib.result Lwt.t

write t ~src ~dst ~ttl buffer sends the ICMP message in buffer to dst over IP. Passes the time-to-live (ttl) to the IP stack if given.
