Struct rustc_errors::DiagInner

pub struct DiagInner {
    pub(crate) level: Level,
    pub messages: Vec<(DiagMessage, Style)>,
    pub code: Option<ErrCode>,
    pub span: MultiSpan,
    pub children: Vec<Subdiag>,
    pub suggestions: Result<Vec<CodeSuggestion>, SuggestionsDisabled>,
    pub args: DiagArgMap,
    pub sort_span: Span,
    pub is_lint: Option<IsLint>,
    pub(crate) emitted_at: DiagLocation,
}

The main part of a diagnostic. Note that Diag, which wraps this type, is used for most operations, and should be used instead whenever possible. This type should only be used when Diag’s lifetime causes difficulties, e.g. when storing diagnostics within DiagCtxt.

Fields

level: Level

messages: Vec<(DiagMessage, Style)>

code: Option<ErrCode>

span: MultiSpan

children: Vec<Subdiag>

suggestions: Result<Vec<CodeSuggestion>, SuggestionsDisabled>

args: DiagArgMap

sort_span: Span

This is not used for highlighting or rendering any error message. Rather, it can be used as a sort key to sort a buffer of diagnostics. By default, it is the primary span of span if there is one. Otherwise, it is DUMMY_SP.

is_lint: Option<IsLint>

emitted_at: DiagLocation

With -Ztrack_diagnostics enabled, we print where in rustc this error was emitted.

Implementations

impl DiagInner

pub fn new<M: Into<DiagMessage>>(level: Level, message: M) -> Self

pub fn new_with_messages( level: Level, messages: Vec<(DiagMessage, Style)> ) -> Self

pub fn level(&self) -> Level

pub fn is_error(&self) -> bool

pub(crate) fn update_unstable_expectation_id( &mut self, unstable_to_stable: &FxIndexMap<LintExpectationId, LintExpectationId> )

pub(crate) fn has_future_breakage(&self) -> bool

Indicates whether this diagnostic should show up in cargo’s future breakage report.

pub(crate) fn is_force_warn(&self) -> bool

pub(crate) fn subdiagnostic_message_to_diagnostic_message( &self, attr: impl Into<SubdiagMessage> ) -> DiagMessage

pub(crate) fn sub( &mut self, level: Level, message: impl Into<SubdiagMessage>, span: MultiSpan )

pub(crate) fn arg( &mut self, name: impl Into<DiagArgName>, arg: impl IntoDiagArg )

fn keys( &self ) -> (&Level, &[(DiagMessage, Style)], &Option<ErrCode>, &MultiSpan, &[Subdiag], &Result<Vec<CodeSuggestion>, SuggestionsDisabled>, Vec<(&DiagArgName, &DiagArgValue)>, &Option<IsLint>)

Fields used for Hash, and PartialEq trait.

Trait Implementations

impl Clone for DiagInner

fn clone(&self) -> DiagInner

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiagInner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for DiagInner

fn decode(__decoder: &mut __D) -> Self

impl<__E: SpanEncoder> Encodable<__E> for DiagInner

fn encode(&self, __encoder: &mut __E)

impl Hash for DiagInner

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DiagInner

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
