Parameter Make.1-T

type t
val hash_fold_t : Base.Hash.state -> t -> Base.Hash.state
val hash : t -> Base.Hash.hash_value
include Hashtbl.Key with type t := t
include Ppx_sexp_conv_lib.Sexpable.S with type t := t
val t_of_sexp : Sexplib0.Sexp.t -> t
val sexp_of_t : t -> Sexplib0.Sexp.t
include Hashtbl_intf.Key_plain with type t := t
val compare : t -> t -> int
val sexp_of_t : t -> Base.Sexp.t
val hash : t -> int

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