§@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.
