Cargo Features

ObjC has no features set by default.

[dependencies]
objc = { version = "0.2.7", features = ["exception", "verify_message"] }
exception = objc_exception
verify_message

Affects message::Message.send_message, message::send_message, message::send_super_message

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
