Function objc2::exception::throw

pub unsafe fn throw(exception: Option<&Id<Object, Shared>>) -> !

Throws an Objective-C exception.

The argument must be a pointer to an Objective-C object.

Safety

This unwinds from Objective-C, and the exception must be caught using an Objective-C exception handler like catch (and specifically not catch_unwind).

This also invokes undefined behaviour until C-unwind is stabilized, see RFC-2945.
