Implementations§

source§

impl SpanRange

source

pub fn single_span(span: Span) -> Self

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

source

pub fn call_site() -> Self

Create a SpanRange resolving at call site.

source

pub fn from_tokens(ts: &dyn ToTokens) -> Self

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.

source

pub fn join_range(self, other: SpanRange) -> Self

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

source

pub fn collapse(self) -> Span

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