Struct syntex_pos::MultiSpan

pub struct MultiSpan {
    // some 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.

Methods

impl MultiSpan

fn new() -> MultiSpan

fn from_span(primary_span: Span) -> MultiSpan

fn from_spans(vec: Vec<Span>) -> MultiSpan

fn push_span_label(&mut self, span: Span, label: String)

fn primary_span(&self) -> Option<Span>

Selects the first primary span (if any)

fn primary_spans(&self) -> &[Span]

Returns all primary spans.

fn replace(&mut self, before: Span, after: Span) -> bool

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

fn span_labels(&self) -> Vec<SpanLabel>

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.

Trait Implementations

impl Clone for MultiSpan

fn clone(&self) -> MultiSpan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<Span> for MultiSpan

fn from(span: Span) -> MultiSpan

Performs the conversion.
