Struct DiagCtxt

pub struct DiagCtxt {
    pub(crate) inner: Lock<DiagCtxtInner>,
}

A DiagCtxt deals with errors and other compiler output. Certain errors (fatal, bug, unimpl) may cause immediate exit, others log errors for later reporting.

Fields

inner: Lock<DiagCtxtInner>

Implementations

impl DiagCtxt

pub fn disable_warnings(self) -> Self

pub fn with_flags(self, flags: DiagCtxtFlags) -> Self

pub fn with_ice_file(self, ice_file: PathBuf) -> Self

pub fn with_registry(self, registry: Registry) -> Self

pub fn new(emitter: Box<DynEmitter>) -> Self

pub fn make_silent( &self, fallback_bundle: LazyFallbackBundle, fatal_note: Option<String>, emit_fatal_diagnostic: bool, )

pub(crate) fn wrap_emitter<F>(&self, f: F)

where F: FnOnce(DiagCtxtInner) -> Box<DynEmitter>,

pub fn eagerly_translate<'a>( &self, message: DiagMessage, args: impl Iterator<Item = DiagArg<'a>>, ) -> SubdiagMessage

Translate message eagerly with args to SubdiagMessage::Eager.

pub fn eagerly_translate_to_string<'a>( &self, message: DiagMessage, args: impl Iterator<Item = DiagArg<'a>>, ) -> String

Translate message eagerly with args to String.

pub fn can_emit_warnings(&self) -> bool

pub fn reset_err_count(&self)

Resets the diagnostic error count as well as the cached emitted diagnostics.

NOTE: do not call this function from rustc. It is only meant to be called from external tools that want to reuse a Parser cleaning the previously emitted diagnostics as well as the overall count of emitted error diagnostics.

pub fn handle<'a>(&'a self) -> DiagCtxtHandle<'a>

pub fn taintable_handle<'a>( &'a self, tainted_with_errors: &'a Cell<Option<ErrorGuaranteed>>, ) -> DiagCtxtHandle<'a>

Link this to a taintable context so that emitting errors will automatically set the Option<ErrorGuaranteed> instead of having to do that manually at every error emission site.

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.
