How did you find learning Rust? You hear a lot about how steep the learning curve is. How suitable is it for web backends? I am just dying to get started with

  Not bad, or bad, depending on how you learn it, what you try to do, etc. In my experience, you can write Rust a lot like you write Go. A little more learning perhaps, because Go will do things "automagically", but you can reference count just like you would in Go/Python and it makes your code _far, far_ simpler. You also can use Rust's "interfaces" (`dyn Foo`) which behave a lot like Go's interfaces of `Foo { }`. You waste a bit of memory, but who cares when you're coming from Go or Python. You aren't trying to write the most efficient program ever (usually). As far as web backends, it's what we use it for at my shop. The only rough part there is framework maturity. The best novice framework (imo) is Rocket, though it's not quite mature. The "best" framework is probably Actix, but it's a bit more complex for newcomers. So yea, my advice is to be careful to learn only what you think you need to know. Don't bite off everything at once. Generics is the same story, learn the basics of what a generic is, how to use it, etc, and then rarely use it. You didn't have them in Go, right? Write Rust like Go. Learning a pinch of everything is useful though so that when a complex annoying thing occurs you have some idea how to handle it or where your knowledge is deficient. Also embracing Rust communities like /r/learnrust/ is useful too. Very friendly. Hope this helps :)
