Trait DropTreeBuilder

trait DropTreeBuilder<'tcx> {
    // Required methods
    fn make_block(cfg: &mut CFG<'tcx>) -> BasicBlock;
    fn link_entry_point(cfg: &mut CFG<'tcx>, from: BasicBlock, to: BasicBlock);
}

A trait that determined how DropTree creates its blocks and links to any entry nodes.

Required Methods

fn make_block(cfg: &mut CFG<'tcx>) -> BasicBlock

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

fn link_entry_point(cfg: &mut CFG<'tcx>, from: BasicBlock, to: BasicBlock)

Links a block outside the drop tree, from, to the block to inside the drop tree.

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.
