Struct DiagCtxtFlags 

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

Flags that control the behaviour of a DiagCtxt.

Fields

can_emit_warnings: bool

If false, warning-level lints are suppressed.

treat_err_as_bug: Option<NonZero<usize>>

If Some, the Nth error-level diagnostic is upgraded to bug-level.

deduplicate_diagnostics: bool

If true, identical diagnostics are reported only once.

track_diagnostics: bool

Track where errors are created. Enabled with -Ztrack-diagnostics, and by default in debug builds.
