attempted writing my small web application in Rust but was unable to interface with the API I needed because they implement an early draft of OAuth 2.0, not OAuth 2.0 itself, and none of the Rust OAuth 2.0 clients implement anything but the final version
given that Rust the language is itself younger than the OAuth 2.0 draft they’re (still) implementing six years after OAuth 2.0 was finalised, I guess this makes sense
