Sorry to say that but Rust community is full of extremists. The 
promises of the Rust language has to taken with grain of salt. 
I've seen many negative opinions about the actual Rust usage.

Let me list just 3 points of the Rust language issues on software 
development(in general):

1. No garbage collector - this means no fully automatic memory 
management (cycles).
2. Despite the Rust funboys' claims a compiler won't fix all 
memory bugs at compile time, just to name array accesses, but 
that is not all.
3. No GUI library because of the language limitations.

Of course any memory safety checks at compile time are nice but I 
would be careful with paying too much for it.

Because of its design Rust seems to be less productive than other 
popular languages .
