Let's start our chapter by bringing the famous Hello World program into the 21st century by hosting it on a server. We are going to use the hyper crate for this, which is a strongly typed wrapper around all things HTTP. In addition to being one of the fastest HTTP implementations in the world (https://www.techempower.com/benchmarks/#section=data-r15&hw=ph&test=plaintext), it is used by nearly all major high-level frameworks (https://github.com/flosse/rust-web-framework-comparison#high-level-frameworks), the only exception being the ones that reimplemented it all on the extremely basic stringly-typed TCP library that Rust provides under std::net::TcpStream.
