Over the years, I've deployed applications using various combinations of custom RPMs, Chef, Heroku, Docker, ECS and Kubernetes. If you can, you should probably deploy to Heroku. (Or a similar service.) It's far cheaper than spendi

Yeah, Rust's musl support is great. We use it heavily at work for all sorts of CLI tools. Many thanks to everybody who worked on this. (And if you need to link against common C libraries like OpenSSL or PostgreSQL, I maintain a Docker

Thank you for checking this, and determining it didn't actually apply in this case. We do a lot of I/O intensive Rust at work, and I have a list of things to double-check when benchmarking. The most common slowdowns: debug builds,

The Rust "edition" flag is set on a per-library ("crate") basis, not per source file. It basically just controls a few small differences at the parser level. I'm really happy about the ability to mix older Rust 2015

So the first question: Why are you using a doubly-linked list? :-) Due to the way modern processors work, following long chains of pointers is massively expensive (unless can you carefully control where all of the memory was allocated). The
