Ping function implemented in rust.

Sending an ICMP package should create a socket of type raw on most platforms. And most of these platforms require special privileges. Basically, it needs to run with sudo on Linux to create a raw socket.

These requirements introduce security risks, so on modern platforms, unprivileged ping has been introduced, with socket type dgram. So there are two mods in this crate, rawsock and dgramsock, which have the same function ping. And the global ping function is just an alias for the rawsock::ping. You can pick the one which is suitable for your use case.

For Linux users, although modern kernels support ping with dgram, in some distributions (like Arch), it's disabled by default. More details: https://wiki.archlinux.org/title/sysctl#Allow_unprivileged_users_to_create_IPPROTO_ICMP_sockets
