But this is a problem Rust creates for itself. HTTP is safely implementable in most modern languages without any unsafe code because they're all garbage collected. For instance, Java has a mechanism also called Unsafe that lets you bypass the language's safety features, but I've never encountered an HTTP client that uses it because performance is fine without that. And the JVM developers have been working for years on safe but performant constructs that can replace the uses of Unsafe that do exist in the community, mostly, cases where very precise control over memory and concurrency constructs are needed in high performance servers.
