> I've been using it for 2 years now and I can't see any loss in productivity
While I am a big fan and all my personal projects are written in Rust, introducing Rust will likely paralyse entire teams for months, until they get used to the borrow checker. ORMs are quite clunky (at least Diesel) and web frameworks are not as user-friendly as ASP.NET MVC, and that’s 80% of what the average developer needs today.
We made a short-term decision to develop a new project in Rust only three months ago.
As we build vending machines and such things, our products usually contain multiple processors that communicate over various connections and there's a lot of interaction with real-world, physical things. Also, as there are a lot of microcontrollers involved, C and C++ are the dominant languages in our development.
So, a lot of our development time actually goes into solving the general unpredictiveness of the real world and humans interacting with actual machines.
Rust enables us to focus on solving those problems without getting held up by stupid memory issues. In our case, iterating over new software versions often is slow because it may involve restarting a big machine and doing actual user interaction with it – the time Rust takes before compiling is easily saved for us.
