Rust has a policy of keeping the standard library minimal and this is completely reasonable. But sometimes they overdo it. In this case it's nuts that I need to implement my own UnixString because the standard library doesn't expose it, and when I run on Linux I have two incompatible versions of the same thing.
Another example: I wrote a command line app which takes a hostname/ip address plus an optional port number after a colon. And the whole thing's async using tokio. The way the hostname/IP address parsing is structured in tokio and the standard library meant I had to reimplement all of it to add the port number. This all feels like more effort than it should be.
