defmodule Combine.ParserState do

  @moduledoc """

  Defines a struct representing the state of the parser.



  The struct has following fields:



    - `input` - the unparsed part of the input

    - `column` - column position of the next character (zero based)

    - `line` - current line position

    - `results` - list of outputs produced by so far, in the reverse order

    - `status` - `:ok` if the grammar rules are satisfied, `:error` otherwise

    - `error` - an error message if a grammar rule wasn't satisfied

  """

    input: binary,

    column: non_neg_integer,

    line: pos_integer,

    results: [any],

    status: :ok | :error,

    error: any
