It's the reverse of what happened with JavaScript. In other words, JavaScript started on the front-end and then spread to the back-end because it was advantageous to have one language for both. One of those advantages is that folks who were experts in JavaScript were suddenly able to use their language of choice for back-end work too.
Rust started on the back-end but is fairly likely to spread to the front-end in the future for the same reason. One of the advantages will again be that folks who are experts in Rust will be able to use their language of choice for front-end work too.
Beyond this, I would argue that Rust's type system is a significant draw for many folks as well. I dare say it has a lot more potential than Elm, a Haskell-like language designed just for web development.
