pub struct MultiSpan { /* private fields */ }
Expand description

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.

Implementations

Selects the first primary span (if any)

Returns all primary spans.

Returns true if this contains only a dummy primary span with any hygienic context.

Replaces all occurrences of one Span with another. Used to move Spans in areas that don’t display well (like std macros). Returns true if replacements occurred.

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.
