@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}
.

- An issue that did not cause failure but suggests the programmer may have made a mistake:hint
- A suggestion for style or good practices that is not as severe as a warning:information
- Any other information relevant to compilation that does not fit into the above categories
