The Rust API bindings are already released, you can find the documentation on our homepage: https://www.tinkerforge.com/en/doc/Software/API_Bindings_Rust.html.
The Go API bindings are not officially released yet, but you can already try the beta version. Check out this forum entry on TinkerUnity: https://www.tinkerunity.org/forum/index.php/topic,4687.msg26407.html
If you always wanted to try Rust or Go, you can now do it with your Tinkerforge Bricks and Bricklets during the holidays :-).
We wish you a Merry Christmas!
