Struct LabeledSpan 

pub struct LabeledSpan {
    pub label: String,
    pub span: Span,
}

A named source range: a label plus a span.

Used in diagnostics to annotate specific regions of source text.

Fields

label: String

Human-readable label for this region.

span: Span

The source span.

Implementations

impl LabeledSpan

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

Construct a new labeled span.

pub fn len(&self) -> usize

Return the length of the underlying span.

pub fn is_empty(&self) -> bool

true if the span is zero-length.

Trait Implementations

impl Clone for LabeledSpan

fn clone(&self) -> LabeledSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LabeledSpan

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

Formats the value using the given formatter.

impl PartialEq for LabeledSpan

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