Whether it can be used like an more FP-style Python/Ruby is one thing but whether it can replace Rails is a whole other question. This website is dedicated to answering that:
(although looking at it again most of the content links are a bit old, but the library stuff seems current)
I think that a Web framework such as Flask (without the ecosystem of its plugins) or even Falcon can be replaced by a Rust app, as of today. But, I totally agree with the rest of the website. Before replacing a Django or a Rails project, there is some work!

Rust has that feel because it is new. I have no doubt that it will look like c++ in a few years. Full of "must have functions and extensions"
Edit: The solution here[1] is a good example of what I'm talking about I think. A lot of what's there is pretty obvious to someone familiar with JS/Ruby/Python/Perl, and they might even use a very similar looking solution. The Rust specific stuff is really the only foreign stuff, so if you assume you would learn that when learning the language, it's a pretty straightforward solution that looks similar enough to be inviting.
