pub enum UnwindAction {
Continue,
Unreachable,
Terminate(UnwindTerminateReason),
Cleanup(BasicBlock),
}
Expand description
Action to be taken when a stack unwind happens.
Variants§
Continue
No action is to be taken. Continue unwinding.
This is similar to Cleanup(bb)
where bb
does nothing but Resume
, but they are not
equivalent, as presence of Cleanup(_)
will make a frame non-POF.
Unreachable
Triggers undefined behavior if unwind happens.
Terminate(UnwindTerminateReason)
Terminates the execution if unwind happens.
Depending on the platform and situation this may cause a non-unwindable panic or abort.
Cleanup(BasicBlock)
Cleanups to be done.
