The request is just 'htt' with the intent 'what to use', which does not name a product or platform, so the right tool cannot be determined yet. The closest matches in the sources relate to HTTP: hyper is a memory-safe Rust HTTP implementation supporting HTTP/1 and HTTP/2 8, and gRPC is an RPC framework built on HTTP/2 3.

A question back: What do you want to use HTTP for: building a web server or client in Rust, calling remote services, or something else, and in which language or platform?
