Wishlist: more visible examples, especially without option tokio

[ydirson]

tokio is mentioned as being optional, and it would be useful for newcomers to get an idea how rust-netlink can be used without it.

I'm reporting this in netlink-proto since it is the one showing example code on docs.rs. It would be really useful to have links to example code more visible, directly on https://github.com/rust-netlink/ which gives a good idea of what's in this project, but not really of where to start (which package doc to look at first, where to find examples to get you started).

Note I did find the async_std example. It does however suffer from the same problem described in #7. Providing ready-to-go Cargo.toml files for all examples would make it really easier for users to try them, and would make it possible to check in CI jobs that they are still up-to-date with current code.

Also maybe a non-async example (e.g. with use polling) can be useful (or an explicit mention that only async style is supported), as not everyone has jumped aboard the async train yet.

This crate is design for internal usage.

The https://github.com/rust-netlink/ has updated with notes for new comer. Please check whether that helps.

I am afraid rust-netlink crates is designed to with tokio and smol in mind. If you have your socket implementation, you may try stuff like:

rtnetlink::new_connection_with_socket() and implement netlink_sys::AsyncSocket.

I haven't play with async_std for years, just don't have time to fix it up. Pull requests are welcome as always.

rust-netlink crates are divided into two parts:

• Packet parsing and emitting: netlink-packet-route, netlink-packet-netfilter, netlink-packet-generic, netlink-packet-audit, netlink-packet-wireguard, netlink-packet-xfrm, etc
• Async communication for linux kernel: rtnetlink, ethtool, wl-nl80211, etc

For non-async/blocking way, we do not have top level wrappin. Please give tokio a try, if your use case require minimum dependency, you need to code your own socket communication and use above packet parsing and emitting crates.
