  3. | EchoRequest of Cstruct.t
  4. | EchoReply of Cstruct.t
  5. | VendorMsg of Vendor.t
  6. | SwitchFeaturesRequest

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
val size_of : t -> int

size_of msg returns the size of msg in bytes when serialized.

val parse : Frenetic_kernel.OpenFlow_Header.t -> string -> xid * t

parse hdr bits parses the body of a message with header hdr from buffer bits.

  • parameter hdr

    Header of the message to be parsed from bits.

  • parameter bits

    string containing a serialized message body.

  • returns

    (xid, message) where xid is the transaction ID.

  • raises Ignored
