rust-analyzer is developed in its own repository. If possible, consider making this change to rust-lang/rust-analyzer instead. cc @rust-lang/rust-analyzer Some changes occurred in src/tools/clippy cc @rust-lang/clippy Some changes occurred to the CTFE / Miri engine cc @rust-lang/miri |
Now that error counts can't go up and down due to stashing/stealing, we have a nice property: (err_count > 0) iff (an ErrorGuaranteed has been produced) So we can now record `ErrorGuaranteed`s within `DiagCtxt` and use that in methods like `has_error`, instead of checking that the count is greater than 0 and calling `unchecked_error_guaranteed` to create the `ErrorGuaranteed`. In fact, we can record a `Vec<ErrorGuaranteed>` and use its length to count the number, instead of maintaining a separate count.
Because it also has a `DiagnosticBuilder` arg, which contains a `dcx` reference. Also rename some `builder` variables as `diag`, because that's the usual name.
Now that we have both `delayed_bug` and `span_delayed_bug`, it makes sense to use the generic term "delayed bug" more.
From `Fatal` to `Error`. It has no functional effect, but `Error` makes more sense and lines up better with the `Warning` level used just above.
