A very small Rust binary indeed (darkcoding.net)

Can we make a Rust program that’s as small as it’s assembler equivalent?

i think nothing can outperform simple asm for simple operations.

IDK, I'm not aware of all the fancy asm commands, but compilers are, so a good compiler will probably produce better code than me. For example, simple loops could turn into a set of SIMD instructions or be unrolled, while I'd naively do a jump loop.
