Ring structures for RRAs The values in the structures are bound to a range
module BoundedFloat = Rrd_utils.BoundedFloatval make : int -> float -> float -> float -> tcreate a ring structure with size record; records initialised to init
val length : t -> intlength (size) of the ring, it is constant
val push : t -> float -> unitpush into the ring one element
val peek : t -> int -> floatget the ith old element from the ring
val top : t -> floatget the top element of the ring
val iter_nb : t -> (float -> unit) -> int -> unititerate over nb element of the ring, starting from the top
val raw_iter : t -> (float -> unit) -> unitval iter : t -> (float -> unit) -> unititerate over all elements of the ring, starting from the top
val get_nb : t -> int -> float arrayget array of latest nb value
val get : t -> float arrayget an array with all the values in the ring
