I applied PGO to many kinds of software, collected a lot of carefully hidden traps on my journey, and found multiple ways how to avoid them. In this talk, I want to share with you my experience.
In this talk, we'll explore reasoning with async Rust. We'll be introduced to its fundamental building blocks, such as `async`, `await`, `join` and `select`, and learn how to predict the behavior of code written with them.
After spending many happy years in Scala, not mutating anything but copying objects faster than rabbits breed I ventured into the world where each allocation is carefully examined and it is perfectly normal to reuse the same list for different purposes.
We will explore some ways to make Async Rust programming more enjoyable and more efficient at the same time.
