Module objc2::exception

@throw and @try/@catch exceptions.

By default, if the msg_send! macro causes an exception to be thrown, this will unwind into Rust, resulting in undefined behavior. However, this crate has an "catch-all" feature which, when enabled, wraps each msg_send! in a @catch and panics if an exception is caught, preventing Objective-C from unwinding into Rust.

Most of the functionality in this module is only available when the "exception" feature is enabled.
