Rust 1.17 - Hackdot

Yeah, semantically you're right. I'm talking about actual binary representation. Some systems/runtimes copy them to the heap/etc while others let you reference the actual memory in the loaded binary.

Back when I did more embedded stuff we cared since it could increase your runtime memory by a non-trival amount depending on what the platform did.

In Rust's case, to be clear, they're stored in .rodata. That's where the &'static str points to.

The auto copy to the heap behavior is controversial, desired by many for ergonomic reasons, disliked by others for implicit heap allocation. We'll see if it gets added in the future or not!

Yeah, you'd find me in the latter camp for sure :).

Thanks for the details, it's appreciated.
