Interface of a unwinding context.

Required methods

fn setup_unwind<T, U>(
    &self,
    extension: &mut impl UnwindInternalAPI<'interface>,
    interface: &mut T,
    f: impl FnOnce(&mut T) -> U + UnwindSafe
) -> U where
    T: CBaseAPI<'interface>, [src]

Sets up the unwinding for the closure f

Any panic or termination signal, that occurs within f, is propagated.

Return

Return value from f.

fn catch_unwind<T, U>(
    &self,
    extension: &mut impl UnwindInternalAPI<'interface>,
    interface: &mut T,
    f: impl FnOnce(&mut T) -> U + UnwindSafe
) -> Result<U, Signal> where
    T: CBaseAPI<'interface>, [src]

Sets up the unwinding for the closure f

Any panic or termination signal, that occurs within f, is caught and returned.

Return

Return value from f or caught signal.
