### Other errors
|
||||
|
||||
Other errors, not previously listed, may occur seldom.
|
||||
|
||||
Most of such errors are due to the unwrapping of ```Result<T>```, which may exceptionally contain the ```Err``` value.
|
||||
|
||||
This may happen in one of the following situations: activation of a pcap ```Capture``` handle, retrieval of network adapters list through pcap, selection of the default device through pcap, creation of the output file, cloning of the output file handle, acquisition of a ```Mutex``` lock, writing of the output file.
|
||||
|
||||
All those exceptional scenarios are managed through calls to the ```expect()``` method, providing textual feedback to the user on the cause of the panic.
