Right now the second link you posted isn't loading, so I'm not sure if that is something that matches the Go Tour interface (maybe it is, and it's not loading because it's failing to init some virtualized environment for test code to run in?).
My problem wasn't that good documentation wasn't available, it certainly is. The first and second editions of the rust book rust book (https://doc.rust-lang.org/book) are what I read through and they're great.
What I meant was very literal -- I don't know of a site with Go tour's exact (or close to exact) interface, where you can run through ~30/40 slides (that's how long go tour is AFAIK) and write some code right in the browser to get a feel for the language.
Rust is considerably more complex than Go, so I'm not sure it could be so succint, but I can say that at least for me, going through Go Tour really did make me feel more confident in starting a project with Golang.
It's not loading because I set up a redirect to its new home, https://doc.rust-lang.org/rust-by-example/, and it seems to work for some people, but not for others. I'll have it fixed sometime soon.
