Addresses returning empty Vec

[egithinji]

Hi! I'm attempting to retrieve the IP address of a device. However the following returns an emtpy vec:
let mut handle = Device::lookup().unwrap();
handle.addresses
I am able however to get the device's name using handle.name.

I was wondering is there a way to retrieve the IP address associated with the device if it's not the above way? Thanks

I'm not sure I fully understand your question, if addresses is empty it's probably mean that this devices don't have any address, you can use https://docs.rs/pcap/0.9.2/pcap/struct.Device.html#method.list and show all devices and their addresses. You may find what you search.

Thanks. Using the list() method has allowed me to retrieve the device's address.
The following still returns an empty vec for the addresses field:
let mut handle = Device::lookup().unwrap();
handle.addresses
However this does return an IP address (and it's the same device that is retrieved):
let mut handle = &Device::list().unwrap()[0];
handle.addresses

But the list() method is perfectly fine for me and has solved my problem, thanks.
