[][src]Struct syntax_pos::MultiSpan

pub struct MultiSpan { /* fields omitted */ }

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.


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 Spans 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.
