pub fn abort_unwind<F: FnOnce() -> R, R>(f: F) -> Rabort_unwind #130338)Expand description
Invokes a closure, aborting if the closure unwinds.
When compiled with aborting panics, this function is effectively a no-op. With unwinding panics, an unwind results in another call into the panic hook followed by a process abort.
§Notes
Instead of using this function, code should attempt to support unwinding.
Implementing Drop allows you to restore invariants uniformly in both
return and unwind paths.
If an unwind can lead to logical issues but not soundness issues, you
should allow the unwind. Opting out of UnwindSafe indicates to your
consumers that they need to consider correctness in the face of unwinds.
If an unwind would be unsound, then this function should be used in order
to prevent unwinds. However, note that extern "C" fn will automatically
convert unwinds to aborts, so using this function isn’t necessary for FFI.
