source · 
trait DropTreeBuilder<'tcx> {
    fn make_block(cfg: &mut CFG<'tcx>) -> BasicBlock;
    fn add_entry(cfg: &mut CFG<'tcx>, from: BasicBlock, to: BasicBlock);
}
Expand description

Required Methods

Create a new block for the tree. This should call either cfg.start_new_block() or cfg.start_new_cleanup_block().
