create ?to_expire () creates a new cache where fragments are kept until to_expire nanoseconds (defaults to 10s).

  t ->
  Key.t ->
  ?last:bool ->
  off:int ->
  len:int ->
  SBstr.t ->
  (Key.t * payload) option

insert ~now cache key ?last ~off ~len slice inserts a new slice into the given cache identified by the given key. The user can specify a sub-view of the given slice and must informs if the payload is the last one or not with the last value (defaults to false).
