Module type Mirage_protocols.ICMPV6

ICMPv6 layer

include Mirage_device.S
type t

The type representing the internal state of the device

val disconnect : t -> unit Lwt.t

Disconnect from the device. While this might take some time to complete, it can never result in an error.

type ipaddr = Ipaddr.V6.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 -> dst:ipaddr -> ?⁠ttl:int -> Cstruct.t -> (unit, error) Stdlib.result Lwt.t

write t 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.
