DoIP - ISO13400-2 is a protocol for diagnostic communication over IP, used in the automotive domain.

DoIP only handles the transmission of diagnostic packets. The actual diagnostic messages is encoded using the UDS (Unified Diagnostic Services) protocol, specified in ISO14229.

Client example

use std::net::Ipv4Addr;
