How to avoid bounds checks in Rust (without unsafe!)

  Shadow is a discrete-event network simulator that directly executes real application code, enabling you to simulate distributed systems with thousands of network-connected processes in realistic and scalable private network experiments using your laptop, desktop, or server running Linux.

I do share this hesitation. I think for simple cases iterators are usually fine, but I've definitely run into cases where an iterator adapter caused unexpected performance problems. e.g. https://github.com/shadow/shadow/pull/2543

Event Tracing for Windows (WPA/xperf) works quite well for profiling, and it's really easy to set up with UIforETW. Symbol loading works with MSVC-generated symbols (just set the target/debug/ folder as a symbol path), though it's rather slow.

I'm not sure that input[..3] will ever work, but let [a, b, c] = input.as_chunks().0[0]; would work if https://github.com/rust-lang/rust/issues/76342 happened to infer the length. And there's ongoing libs discussion about some sort of let [a, b, c] = input.prefix::<3>().unwrap();.
