I like its immutability by default. But I don't like the syntax. Adding mut to a variable declaration makes it mutable, but nowhere else you can see you are dealing with a dangerous variable. Or I am a bit biased toward Elixir.
Rust sounds otherwise really cool, and I like its package manager. But I am not going to use it anytime soon. Sticking to Node.js and Elixir for a while I guess.
