[Feature Request] provide current RX/TX bytes for each interface

[jin-eld]

Hi,

thank you for this great crate, this is exactly what I was looking for in cross platform environments.

Would you consider providing the current RX/TX byte count of the interface? This would be very useful for monitoring traffic and right now I have to combine netdev and sysinfo, because the latter has RX/TX, but does not expose the interface index in the API (which I also need), while netdev does give me the interface index, but does not offer RX/TX values. It'd be great if I could only stick with netdev without having to cross-reference interface lists from both crates in order to populate what is missing 😅

Kind regards,
Jin

Thank you for your request!

In fact, this is a feature I had been contemplating for quite some time — mainly because I’ve been carefully considering what the scope of netdev should be as it moves toward a stable v1.0.
On one hand, I wanted to keep it lean and focused; on the other hand, I completely understand how frustrating it is to have to juggle multiple crates to get complete information per interface.

So, after giving it more thought — I’ve decided to go ahead and add RX/TX byte counters to netdev.

It will likely take the form of a new optional field within the Interface struct, or possibly a separate API depending on platform performance characteristics. Cross-platform implementation will be incremental, starting with Linux, and then moving on to Windows and macOS.

Awesome, thank you!

Hi!
I’ve just released v0.36.0, which includes support for interface traffic statistics (RX/TX bytes).
You can now access them via the new stats field on the Interface struct.

Please see the documentation for details:

Wow, this was fast, works great, thank you!
