    An async traceroute(1) implementation in Rust▲9

    I wrote a minimal traceroute(1) clone that leans on asynchrony to reduce the time spent tracing a route. Underneath, it uses ICMP to do its job. The plan is to add support for UDP tracing and a path maximum transmission unit discovery mechanism. Comments and suggestions are welcome!
