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 true, error-level diagnostics are 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 delay_span_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.

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.
