[−][src]Struct objc::MessageError
An error encountered while attempting to send a message.
Currently, an error may be returned in two cases:
- an Objective-C exception is thrown and the
exceptionfeature is enabled - the encodings of the arguments do not match the encoding of the method
and the
verify_messagefeature is enabled
