Struct rustc_span::MultiSpan[][src]

pub struct MultiSpan {
    primary_spans: Vec<Span>,
    span_labels: Vec<(Span, String)>,
}
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.

Fields

primary_spans: Vec<Span>span_labels: Vec<(Span, String)>

Implementations

Selects the first primary span (if any).

Returns all primary spans.

Returns true if any of the primary spans are displayable.

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 whether 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.

Returns true if any of the span labels is displayable.

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
