Thanks for sharing. As a Rust learner, I still don't know how to place the cursor between performance with borrowing and ergonomic with copying. Most of the time, I just copy/clone and I tell myself that the performance does not matter that much because it will be fast enough for my purpose anyway.

> it will be fast enough for my purpose anyway It probably will be. I've been using Rust in production for a while now, and our bottlenecks are never Rust's performance. Something else is the bottleneck way before we approach anything close to Rust's peak throughput. This is especially true if you're doing anything that touches networking or interacts with other services.

  We've used this to our advantage when performance testing things on the JVM. We might not write the final solution in Rust, but we'll use it to figure out a theoretical upper limit with various things like Kafka and misc. databases.
