Re: Rust, Curl is modular enough that you don't need to rewrite it in Rust in order to enjoy some of its benefits, you can just tell Curl to use Hyper (Rust's de-facto HTTP lib) as a backend. For the past few years they've been working on getting the Hyper backend to pass the Curl test suite and they're down to five remaining tests, so perfect support looks to be imminent: https://github.com/orgs/hyperium/projects/2/views/1 (seanmonstar occasionally streams on Twitch if you'd like to watch him work on these).
