Rename many `DiagCtxt` arguments.

2023-12-18T05:06:22+00:00

Rename `Handler` as `DiagCtxt`.

2023-12-18T05:06:19+00:00

Avoid `struct_diagnostic` where possible.

2023-12-14T04:53:55+00:00

It's necessary for `derive(Diagnostic)`, but is best avoided elsewhere because there are clearer alternatives. This required adding `Handler::struct_almost_fatal`.

Support async gen fn

Make async gen fn an error

2023-12-04T19:23:07+00:00

De-genericize some `IntoDiagnostic` impls.

2023-12-04T07:57:42+00:00

These impls are all needed for just a single `IntoDiagnostic` type, not a family of them. Note that `ErrorGuaranteed` is the default type parameter for `IntoDiagnostic`.

Account for `(pat if expr) => {}`

2023-11-29T18:47:32+00:00

When encountering match arm (pat if expr) => {}, recover and suggest removing parentheses. Fix #100825.

More accurate span for unnecessary parens suggestion
