(** {2 Hash Types} *)
(** The signature of an abstract hash type, as produced by functor
{!Make_Blake2B}. The {!t} type is abstracted for separating the
various kinds of hashes in the system at typing time. Each type is
equipped with functions to use it as is of as keys in the database
or in memory sets and maps. *)
