Module Ocaml_parsing.Asttypes

Auxiliary AST types used by parsetree and typedtree.

Warning: this module is unstable and part of compiler-libs.

type constant =
  1. | Const_int of int
  2. | Const_char of char
  3. | Const_string of string * Ocaml_parsing.Location.t * string option
  4. | Const_float of string
  5. | Const_int32 of int32
  6. | Const_int64 of int64
  7. | Const_nativeint of nativeint
type rec_flag =
  1. | Nonrecursive
  2. | Recursive
type direction_flag =
  1. | Upto
  2. | Downto
type private_flag =
  1. | Private
  2. | Public
type mutable_flag =
  1. | Immutable
  2. | Mutable
type virtual_flag =
  1. | Virtual
  2. | Concrete
type override_flag =
  1. | Override
  2. | Fresh
type closed_flag =
  1. | Closed
  2. | Open
type label = string
type arg_label =
  1. | Nolabel
  2. | Labelled of string
    (*

    label:T -> ...

    *)
  3. | Optional of string
    (*

    ?label:T -> ...

    *)

This is used only in the Parsetree.
