Struct Diagnostic 

#[non_exhaustive]
pub struct Diagnostic { /* private fields */ }

A parser or lexer diagnostic anchored in source text.

Constructed by SourceFile::parse; read fields through accessors so future metadata (severity, codes, notes) can be added without breaking callers. Diagnostic positions are 1-based Unicode scalar columns; byte ranges remain available through Diagnostic::range.

Implementations

impl Diagnostic

pub const fn range(&self) -> TextRange

Byte range of the diagnostic in source text.

pub const fn line(&self) -> LineNumber

1-based line number of the diagnostic start.

pub const fn column(&self) -> CharColumn

1-based character column of the diagnostic start.

pub const fn end_column(&self) -> DiagnosticEndColumn

End-column shape for the diagnostic span.

DiagnosticEndColumn::SameLineEnd contains the exclusive 1-based Unicode-scalar column for non-empty same-line spans. Empty and multi-line spans are reported as distinct variants instead of a nullable column.

pub fn message(&self) -> &str

Human-readable diagnostic message.

pub const fn category(&self) -> DiagnosticCategory

Parser diagnostic category from daml-parser.

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 Eq for Diagnostic

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.
