The two kinds of delayed bug have quite different semantics so a stronger conceptual separation is nice. (`is_error` is a good example, because the two kinds have different behaviour.) The commit also moves the `DelayedBug` variant after `Error` in `Level`, to reflect the fact that it's weaker than `Error` -- it might trigger an error but also might not. (The pre-existing `downgrade_to_delayed_bug` function also reflects the notion that delayed bugs are lower/after normal errors.) Plus it condenses some of the comments on `Level` into a table, for easier reading, and introduces `can_be_top_or_sub` to indicate which levels can be used in top-level diagnostics vs. subdiagnostics. Finally, it renames `DiagCtxtInner::span_delayed_bugs` as `DiagCtxtInner::delayed_bugs`. The `span_` prefix is unnecessary because some delayed bugs don't have a span. |
