Rust – Compile Time Memory Safety
The author says that this is "why Rust is interesting".  I've done a little bit with Rust -- no production code, but some simulations and things like that.  While compile time memory safety was the first thing to interest me in Rust, I don't even think it's the primary selling point anymore.  The selling point to me is that nearly everything behaves in predictable ways.E.g. since immutable references are the default, you immediately know whether or not a call will modify its argument.  E.g. the existence of traits and compiler warnings for style mean that method naming conventions are incentivized, because implementing a trait usually gives you a lot for free.  Even performance characteristics are very predictable, a statement which I can only otherwise make about C and assembly (and those are not predictable at all in other ways).Yes, the memory safety does play into this.  It's much more than that, though:  memory safety is just one factor in a kind of pervasive predictability that the language encourages through its very design.
