Struct Diagnostic 

pub struct Diagnostic {
    pub severity: Severity,
    pub message: String,
    pub primary_span: Span,
    pub labels: Vec<Label>,
}

Strukturierte Diagnose-Meldung.

Modelliert nach rustc-Diagnostics: ein Schweregrad, eine Hauptbotschaft, ein primary-Span und beliebig viele zusaetzliche Labels mit eigenem Text.

Fields

severity: Severity

Schweregrad.

message: String

Kompakter Text (eine Zeile, ohne Punkt am Ende).

primary_span: Span

Primary-Anker im Source-Text.

labels: Vec<Label>

Zusaetzliche Anker mit Erlaeuterungen.

Implementations

impl Diagnostic

pub fn error(message: impl Into<String>, primary_span: Span) -> Self

Konstruktor fuer Fehler-Diagnostiken.

pub fn warning(message: impl Into<String>, primary_span: Span) -> Self

Konstruktor fuer Warnung-Diagnostiken.

pub fn with_label(self, span: Span, message: impl Into<String>) -> Self

Builder-Methode: zusaetzliches Label anhaengen.

Trait Implementations

impl Clone for Diagnostic

fn clone(&self) -> Diagnostic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Diagnostic

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

Formats the value using the given formatter.

impl PartialEq for Diagnostic

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

Tests for self and other values to be equal, and is used by ==.

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

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