Class type

An abstract unique identifier based on ordinary OCaml integers. Be careful, this may easily overflow on 32-bit platforms! Int63 is a safer choice for portability.

Int is useful when one is passing unique ids to C and needs a guarantee as to their representation. Int is always represented as an integer, while Int63 is either an integer (on 64-bit machines) or a pointer (on 32-bit machines).

The generated ids will therefore be fast to generate and not use much memory. If you do not have very stringent requirements on the size, speed, and ordering of your IDs then you should use the UUIDM library instead, which will give you a truly unique id, even amongst different runs and different machines.

Parameters

Signature

type t = private Base.Int.t

The sexps and strings look like integers.

include Bin_prot.Binable.S with type t := t
include Bin_prot.Binable.S_only_functions with type t := t
val bin_size_t : t Bin_prot.Size.sizer
val bin_write_t : t Bin_prot.Write.writer
val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

val bin_shape_t : Bin_prot.Shape.t
val bin_writer_t : t Bin_prot.Type_class.writer
val bin_reader_t : t Bin_prot.Type_class.reader
include Ppx_hash_lib.Hashable.S with type t := t
include Sexplib0.Sexpable.S with type t := t
val t_of_sexp : Sexplib0__.Sexp.t -> t
val sexp_of_t : t -> Sexplib0__.Sexp.t
include Typerep_lib.Typerepable.S with type t := t
val typename_of_t : t Typerep_lib.Typename.t

Caveat: values created with of_float, of_sexp, or of_string may be equal to previously created values.

include Comparable.S_binable with type t := t
include Base.Comparable.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 equal : t -> t -> bool
val compare : t -> t -> int
val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int
val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool
val clamp_exn : t -> min:t -> max:t -> t

type comparator_witness
val validate_lbound : min:t Maybe_bound.t -> t Validate.check

include Hashable.S_binable with type t := t

val hash_fold_t : t Base__Ppx_hash_lib.hash_fold
val hash : t -> Base__Ppx_hash_lib.Std.Hash.hash_value
val hashable : t Core__.Hashtbl.Hashable.t
module Table : Hashtbl.S_binable with type key = t
module Hash_set : Hash_set.S_binable with type elt = t
module Hash_queue : Hash_queue.S with type key = t
val of_int_exn : int -> t
val to_int_exn : t -> int
val of_string : string -> t
val to_string : t -> string
val create : Base.Unit.t -> t

Always returns a value that is not equal to any other value created with create.
