Parameter Make.T

type t
include Ppx_hash_lib.Hashable.S with type t := t
val hash_fold_t : Base.Hash.state -> t -> Base.Hash.state
include Hashtbl.Key with type t := t
include Sexplib0.Sexpable.S with type t := t

include Hashtbl_intf.Key_plain with type t := t
val compare : t -> t -> int
val sexp_of_t : t -> Sexplib0.Sexp.t
val hash : t -> int

Two ts that compare equal must have equal hashes for the hashtable to behave properly.
