One typically obtains a Source_code_position.t using a [%here] expression, which is implemented by the ppx_here preprocessor.

type t = Caml.Lexing.position = {
  1. pos_fname : string;
  2. pos_lnum : int;
  3. pos_bol : int;
  4. pos_cnum : int;
}

See INRIA's OCaml documentation for a description of these fields.

sexp_of_t uses the form "FILE:LINE:COL", and does not have a corresponding of_sexp.

-1 means "less than", 0 means "equal", 1 means "greater than", and other values should not be returned

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~cmp:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool
val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val clamp : t -> min:t -> max:t -> t Or_error.t
include Comparator.S with type t := t
type comparator_witness
include Comparable_intf.Validate with type t := t
val validate_lbound : min:t Maybe_bound.t -> t Validate.check
val validate_ubound : max:t Maybe_bound.t -> t Validate.check
val validate_bound : min:t Maybe_bound.t -> max:t Maybe_bound.t -> t Validate.check
val to_string : t -> string

to_string t converts t to the form "FILE:LINE:COL".
