type t = {
cmd : cmd;
p1 : int;
p2 : int;
lc : int;
le : int;
data : Cstruct.t;
}

Type of an ADPU.

val max_data_length : int

max_data_length is the maximum data length of an APDU.

val create : ?p1:int -> ?p2:int -> ?lc:int -> ?le:int -> ?data:Cstruct.t -> cmd -> t
val create_string : ?p1:int -> ?p2:int -> ?lc:int -> ?le:int -> ?data:string -> cmd -> t
val length : t -> int

length t is the size of t in bytes.

val write : Cstruct.t -> t -> Cstruct.t

write cs t writes t at cs and returns cs shifted by length t bytes.
