val pp : Format.formatter -> t -> unit
val create : namespace:string -> t

create ~namespace create a digest initialized with the given namespace. Since a caching service is using a flat namespace of keys, the namespace parameter is used to distinguish data build by different functions that have the same parameters digests. A module name is a good candidate for the namespace.

val add : t -> ('a, Format.formatter, unit, t) Core_kernel.Std.format4 -> 'a

add digest fmt x y z ... is a variadic function that builds a string from arguments x y z ... using specified format fmt and adds this string to the digest.

val add_sexp : t -> ('a -> Core_kernel.Std.Sexp.t) -> 'a -> t

add_sexp d sexp_of x is add d "%a" Sexp.pp (sexp_of x)
