pub unsafe fn throw(exception: Retained<Exception>) -> !Available on crate feature
exception only.Expand description
Throws an Objective-C exception.
This is the Objective-C equivalent of Rust’s panic!.
§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 - you can try this out on nightly using the unstable-c-unwind
feature flag.
