Predefined Hashes

val name : string
val title : string
val pp : Stdlib.Format.formatter -> t -> unit
val pp_short : Stdlib.Format.formatter -> t -> unit
include Tezos_stdlib.Compare.S with type t := t
val (=) : t -> t -> bool
val (<>) : t -> t -> bool
val (<) : t -> t -> bool
val (<=) : t -> t -> bool
val (>=) : t -> t -> bool
val (>) : t -> t -> bool
val compare : t -> t -> int
val equal : t -> t -> bool
val max : t -> t -> t
val min : t -> t -> t
val hash_bytes : ?key:Stdlib.Bytes.t -> Stdlib.Bytes.t list -> t
val hash_string : ?key:string -> string list -> t

hash_string ?key inputs returns a hash.

Raises an Assert_failure if String.length key > 64.

Building Hashes

The parameters for creating a new Hash type using Make_Blake2B. Both name and title are only informative, used in error messages and serializers.

module type Name = Tezos_crypto.Blake2B.Name
module type PrefixedName = Tezos_crypto.Blake2B.PrefixedName
module Make_minimal = Tezos_crypto.Blake2B.Make_minimal

Builds a new Hash type using Blake2B.

module type Register = Tezos_crypto.Blake2B.Register
module Make (Register : sig ... end) (Name : PrefixedName) : sig ... end
