Most haskellers are fond of Rust. However, it is certainly not a Haskell replacement; it has substantially less expressive power. This is, arguably, necessary for its impressive memory model (no GC and memory safe allocation), but it does hurt programmer productivity in many cases. I always feel constrained when I use Rust, although I can't fault the language for being that way. Rust is well-designed, but even good designs come with caveats. I prefer Haskell's caveats for most common programming tasks.

Personally, as a frequent Haskell user, I'm looking forward to replacing embedded C/C++ with Rust as soon as they get the AVR toolchain figured out and there's better support for common ARM uCs.
