Implementations

impl Diagnostic

pub fn new( level: Level, file: FileId, range: Range<usize>, message: impl Into<String>, ) -> Self

Create a new diagnostic

pub fn error( file: FileId, span: Range<usize>, message: impl Into<String>, ) -> Self

Create a new error, at the provided location

pub fn warning( file: FileId, span: Range<usize>, message: impl Into<String>, ) -> Self

Create a new warning, at the provided location

pub fn text(&self) -> &str

The diagnostic’s message text

pub fn span(&self) -> Range<usize>

The location of the main span, as a Range<usize>

pub fn is_error(&self) -> bool

true if this diagnostic is an error

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.
