Error

Fields

§lint: bool

If this error comes from a lint, don’t abort compilation even when abort_if_errors() is called.

§

Warning(Option<LintExpectationId>)

This LintExpectationId is used for expected lint diagnostics, which should also emit a warning due to the force-warn flag. In all other cases this should be None.

§

Note

§

OnceNote

A note that is only emitted once.
