Struct SourceDiagnostic 

pub struct SourceDiagnostic {
    pub span: Span,
    pub severity: DiagnosticSeverity,
    pub message: String,
    pub code: Option<String>,
    pub related: Vec<(Span, String)>,
}

A diagnostic message with a source location.

Fields

span: Span

Span of the diagnostic.

severity: DiagnosticSeverity

Severity level.

message: String

The diagnostic message.

code: Option<String>

Optional code (e.g. “E001”).

related: Vec<(Span, String)>

Optional related spans (e.g. for “note” entries).

Implementations

impl SourceDiagnostic

pub fn new( span: Span, severity: DiagnosticSeverity, message: impl Into<String>, ) -> Self

Create a new diagnostic.

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

Create an error diagnostic.

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

Create a warning diagnostic.

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

Create an informational diagnostic.

pub fn with_code(self, code: impl Into<String>) -> Self

Set the error code.

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

Add a related location.

pub fn is_error(&self) -> bool

Whether this is an error.

pub fn is_warning(&self) -> bool

Whether this is a warning.

Trait Implementations

impl Clone for SourceDiagnostic

fn clone(&self) -> SourceDiagnostic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceDiagnostic

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

Formats the value using the given formatter.

impl PartialEq for SourceDiagnostic

fn eq(&self, other: &SourceDiagnostic) -> 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.
