type t
type buffer = Cstruct.t

we expect all serialization and deserialization to happen through Cstruct.t

val pp : Format.formatter -> t -> unit
val create : ?requests:Dhcp_wire.option_code list -> Macaddr.t -> t * buffer

create mac returns a pair of t, buffer. t represents the current * state of the client in the lease transaction, and buffer is the suggested * next packet the caller should take to progress toward accepting a lease.

val input : t -> buffer -> t * buffer option

input t buf attempts to advance the state of t * with the contents of buf. If buf is valid input to the * DHCP input parser and the information within is useful given the * current state of t, the state will be advanced and a new Some packet * suggested for the caller to send. * If not, the previous t will be returned with None.

val lease : t -> Dhcp_wire.pkt option

lease t will return Some lease if t has succeeded in * completing a lease transaction with some server. * Note that the library has no sense of the passage of time, so expiration * is not considered; there is no guarantee that Some lease is still * valid on the network. The caller is responsible for keeping track of * time time at which the lease was obtained, and renewing the lease when * necessary. * If t hasn't yet completed a lease transaction, None will be returned.
