Create utun device on macos.
In Cargo.toml include:
mac_utun = "0.6"
Import the get_utun function:
use mac_utun::get_utun;Just need to call this function. It will search for the first available utun-device starting from 0. As you may know, root permission is necessary to create a utun-device.
pub fn get_utun() -> Result<(UdpSocket,String)>In case of error, the last OS-Error will be returned. In case of success, an UDP-socket and the interface name (e.g. "utun0") will be returned.
UDP-socket is a nice choice, because rust will perform the necessary clean up itself.
There is only one test case defined:
It checks the list of network interfaces before, during and after utun is opened. Expected behaviour: The returned utun is only in the list during utun is opened.
