val int32_manager : int32 data_manager
(** Represents an [int32] as one-element [int32_array] *)
val int64_manager : int64 data_manager
(** Represents an [int64] as two-element [int32_array] *)
val nativeint_manager : nativeint data_manager
(** Uses either [int32_manager] or [int64_manager] to represent [nativeint],

val int_manager : int data_manager
(** Uses either [int32_manager] or [int64_manager] to represent [int],

val int32_array_manager : Netshm.int32_array data_manager
(** The identity representation manager *)
val string_manager : string data_manager
(** Represents a string in the following way. The first element
* is the size of the string. The following elements store the
* bytes. The last word is filled up with zero bytes if necessary.
*)
val pair_manager : 'a data_manager -> 'b data_manager -> ('a * 'b) data_manager
(** Creates a compound manager for pairs from two input managers *)
val left_pair_manager : 'a data_manager -> 'a data_manager
(** Uses the same representation as [pair_manager], but the resulting
* data manager only reads the left value of the pair.
*
* This data manager does not support [to_int32_array].
*)
val option_manager : 'a data_manager -> 'a option data_manager
(** Creates a data manager from an input data manager for optional values *)
