Trait GetSpan

pub trait GetSpan: Sized {
    // Required method
    fn span(&self) -> Span;

    // Provided methods
    fn span_as(self, dst: &mut impl SetSpan) -> Self { ... }
    fn span_region(&self) -> (Span, Span) { ... }
}

General implementations of TokenTree::span

Required Methods

fn span(&self) -> Span

Call TokenTree::span

Provided Methods

fn span_as(self, dst: &mut impl SetSpan) -> Self

*dst = self.span()

fn span_region(&self) -> (Span, Span)

For Group, it will return (span_open, span_close)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
