pub struct SpanRange {
    pub first: Span,
    pub last: Span,
}

Fields

first: Spanlast: Span

Implementations

Create a range with the first and last spans being the same.

Create a SpanRange resolving at call site.

Construct span range from a TokenStream. This method always preserves all the range.

Note

If the stream is empty, the result is SpanRange::call_site(). If the stream consists of only one TokenTree, the result is SpanRange::single_span(tt.span()) that doesn’t lose anything.

Join two span ranges. The resulting range will start at self.first and end at other.last.

Collapse the range into single span, preserving as much information as possible.
