Struct rustc_mir::interpret::eval_context::SpanGuard [−][src]
Implementations
impl SpanGuard[src]
fn new() -> Self[src]
By default a SpanGuard does nothing.
fn enter(&mut self, span: Span)[src]
If a span is entered, we exit the previous span (if any, normally none) and enter the
new span. This is mainly so we don’t have to use Option for the tracing_span field of
Frame by creating a dummy span to being with and then entering it once the frame has
been pushed.
