If I can piggyback on this, as someone who's learning Rust right now:

One of my first trial programs in any language is a tcptraceroute, since it's a good mix of super-beginner tasks and one slightly advanced thing. I hit a problem in Rust right at the beginning: obviously I need to make a socket, but which crate do I use, "socket" or "socket2"? Socket doesn't build anymore, but it's still available as a crate and I have to include it as a dependency and "cargo build" my project to find out that it doesn't work. To make it more frustrating, the only other example of a Rust traceroute that I found uses socket, not socket2, so it doesn't build anymore, either.

I did figure it out, but it felt like an unnecessary speedbump.
