position()

@type position() ::
  nil
  | pos_integer()
  | {pos_integer(), non_neg_integer(), pos_integer(), non_neg_integer()}

Where in a file the diagnostic applies. Can be either a line number, a range specified as {start_line, start_col, end_line, end_col}, or nil if unknown.

Line numbers are one-based, and column numbers in a range are zero-based and refer to the cursor position at the start of the character at that index. For example, to indicate that a diagnostic applies to the first n characters of the first line, the range would be {1, 0, 1, n}.
