[−][src]Struct syntax::source_map::MultiSpan
A collection of spans. Spans have two orthogonal attributes:
- They can be primary spans. In this case they are the locus of
the error, and would be rendered with
^^^
. - They can have a label. In this case, the label is written next to the mark in the snippet when we render.
Methods
impl MultiSpan
[src]
pub fn new() -> MultiSpan
[src]
pub fn from_span(primary_span: Span) -> MultiSpan
[src]
pub fn from_spans(vec: Vec<Span>) -> MultiSpan
[src]
pub fn push_span_label(&mut self, span: Span, label: String)
[src]
pub fn primary_span(&self) -> Option<Span>
[src]
Selects the first primary span (if any).
pub fn primary_spans(&self) -> &[Span]
[src]
Returns all primary spans.
pub fn has_primary_spans(&self) -> bool
[src]
Returns true
if any of the primary spans are displayable.
pub fn is_dummy(&self) -> bool
[src]
Returns true
if this contains only a dummy primary span with any hygienic context.
pub fn replace(&mut self, before: Span, after: Span) -> bool
[src]
Replaces all occurrences of one Span with another. Used to move Span
s in areas that don't
display well (like std macros). Returns whether replacements occurred.
pub fn span_labels(&self) -> Vec<SpanLabel>
[src]
Returns the strings to highlight. We always ensure that there
is an entry for each of the primary spans -- for each primary
span P
, if there is at least one label with span P
, we return
those labels (marked as primary). But otherwise we return
SpanLabel
instances with empty labels.
pub fn has_span_labels(&self) -> bool
[src]
Returns true
if any of the span labels is displayable.
