The answer to 90% of questions about #rustlang is "Because it allows memory safety with zero overhead". (i.e. no GC.)
@mraleph @true_droid @psnively No, overhead versus manual memory management. I suspect global stop the world GC would be worse.

@mraleph@true_droid@psnively i.e. during layout the ref counts remain untouched. Whereas with thread safe GC you must stop the world. -
