Trait rustc::middle::expr_use_visitor::DelegateExperimental

pub trait Delegate<'tcx> {
    fn consume(&mut self, consume_id: NodeId, consume_span: Span, cmt: cmt<'tcx>, mode: ConsumeMode);
    fn matched_pat(&mut self, matched_pat: &Pat, cmt: cmt<'tcx>, mode: MatchMode);

}

This trait defines the callbacks you can expect to receive when employing the ExprUseVisitor.
