Struct DiagCtxtFlags 

Source 
pub struct DiagCtxtFlags {
    pub can_emit_warnings: bool,
    pub treat_err_as_bug: Option<NonZero<usize>>,
    pub eagerly_emit_delayed_bugs: bool,
    pub macro_backtrace: bool,
    pub deduplicate_diagnostics: bool,
    pub track_diagnostics: bool,
}

Fields§

§can_emit_warnings: bool

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

§treat_err_as_bug: Option<NonZero<usize>>

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

§eagerly_emit_delayed_bugs: bool

Eagerly emit delayed bugs as errors, so that the compiler debugger may see all of the errors being emitted at once.

§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.
