We're using [inline assembly] here to load the value from the `rsp` register into `stack_frame`. The syntax is a bit strange, so here's a quick explanation:
[inline assembly]: https://doc.rust-lang.org/nightly/book/inline-assembly.html
[inline assembly]: https://doc.rust-lang.org/1.10.0/book/inline-assembly.html
- The `asm!` macro emits raw assembly instructions. This is the only way to read raw register values in Rust.
- We insert a single assembly instruction: `mov $0, rsp`. It moves the value of `rsp` to some register (the `$0` is a placeholder for an arbitrary register, which gets filled by the compiler).
