Function local_ip_address::local_ip

pub fn local_ip() -> Result<IpAddr, Error>

Retrieves the local IPv4 address of the machine in the local network from the AF_INET family.

A different approach is taken based on the operative system.

For linux based systems the Netlink socket communication is used to retrieve the local network interface.

For BSD-based systems the getifaddrs approach is taken using libc

For Windows systems Win32’s IP Helper is used to gather the Local IP address
