Learning Rust is a good exercise in understanding memory safety. Learning it will make you understand the gotchas of what can go wrong with memory allocation, which will translate very well to coding in other languages, especially C.

Just like learning Haskel is a good exercise in understanding functional programming and lazy evaluation, which again will translate very well to the code you write as you will be able to identify pattens where functional programming can be applied.

However, neither language is really super applicable to general development, because there are hoops you have to jump through to write basic code where the language advantages are not really need, and other languages are much simpler and faster to develop in.

Golang is much more widely used for this reason, as its compiled yet features a gc, simpler to develop in with java contains a lot of good functionality in its stdlib.
