- The C compiler, when I parse a &(float) as (long) (it’s actually an evil floating point hack to run Quake III on an X86_64 CPU emulated in Scratch running on Spotifys Car Thing) (This would never be possible in Rust)

Yes, but
- it’s unsafe, therefore not really Rust I’d argue
- it doesn’t look as good
float Q_rsqrt(float number) {
long i;
float x2, y;
const float threehalfs = 1.5F;
x2 = number * 0.5F;
y = number;
i = * ( long * ) &y;
i = 0x5f3759df - ( i >> 1 );
y = * ( float * ) &i;
y = y * ( threehalfs - ( x2 * y * y ) );
return y;
}

Please don’t tell me you, unironically, actually use the Carmack rsqrt function in the year of our Linux Desktop 2024.
Also if you like, you can write unsafe Rust in safe Rust instead.
