Nicholas Nethercote a8ce44f7d9 Simplify graphviz::Formatter. ... `Formatter` currently has a `RefCell<Option<Results>>` field. This is so the `Results` can be temporarily taken and put into a `ResultsCursor` that is used by `BlockFormatter`, and then put back, which is messy. This commit changes `Formatter` to have a `RefCell<ResultsCursor>` and `BlockFormatter` to have a `&mut ResultsCursor`, which greatly simplifies the code at the `Formatter`/`BlockFormatter` interaction point in `Formatter::node_label`. It also means we construct a `ResultsCursor` once per `Formatter`, instead of once per `node_label` call. The commit also: - documents the reason for the `RefCell`; - adds a `Formatter::body` method, replacing the `Formatter::body` field.		2024-10-30 13:19:29 +11:00
