Write a driver or i/o for an mcu?
Unless most is already done i don't see rust at present able to make something scalable.
And that's not about rust it's about mcu's.....
I could be wrong though.
But it's supported so some cool learning can go on.....

I haven't kept up with the points lately.
But over the years there have been many Discussions about the handling of pointers which should be seen as just another variable.
Mainly in languages develped after C.
