Fields§

§can_emit_warnings: bool

If false, warning-level lints are suppressed. (rustc: see --allow warnings and --cap-lints)

§treat_err_as_bug: Option<NonZeroUsize>

If Some, the Nth error-level diagnostic is upgraded to bug-level. (rustc: see -Z treat-err-as-bug)

§dont_buffer_diagnostics: bool

If true, immediately emit diagnostics that would otherwise be buffered. (rustc: see -Z dont-buffer-diagnostics and -Z treat-err-as-bug)

§report_delayed_bugs: bool

If true, immediately print bugs registered with span_delayed_bug. (rustc: see -Z report-delayed-bugs)

§macro_backtrace: bool

Show macro backtraces. (rustc: see -Z macro-backtrace)

§deduplicate_diagnostics: bool

If true, identical diagnostics are reported only once.

§track_diagnostics: bool

Track where errors are created. Enabled with -Ztrack-diagnostics.
