Bug

DelayedBug

Fatal

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.

Help

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
