Function rustc_query_impl::make_query::source_span

pub fn source_span<'tcx>(
    tcx: QueryCtxt<'tcx>, 
    key: source_span<'tcx>
) -> QueryStackFrame

Return the span for a definition. Contrary to def_span below, this query returns the full absolute span of the definition. This span is meant for dep-tracking rather than diagnostics. It should not be used outside of rustc_middle::hir::source_map.
