Rust High Performance

Extra Performance Enhancements

Once your application avoids common performance bottlenecks, it's time to move to more complex performance improvements. Rust has many options that allow you to improve the performance of your code by using lesser-known APIs. This will give you parity with C/C++ and, in some scenarios, it can even improve the speed of most of the fastest C/C++ scripts.

In this chapter, we will be looking into the following topics:

  • Compile-time checks
  • Compile-time state machines
  • Extra performance enhancements, such as using closures for avoiding runtime evaluation
  • Unstable sorting
  • Map hashing
  • Standard library collections

Compile-time checks

Rust has an amazing type system. It's so powerful that it is Turing-complete by itself. This means that you can write very complex programs just by using Rust's type system. This can help your code a lot, since the type system gets evaluated at compile time, making your runtime much faster.

Starting from the basics, what do we mean by the type system? Well, it means all those traits, structures, generics, and enums you can use to make your code very specialized at runtime. An interesting thing to know is the following: if you create a generic function that gets used with two different types, Rust will compile two specific functions, one for each type.

This might seem like code duplication but, in reality, it is usually faster to have a specific function for the given type than to try to generalize a function over multiple ones. This also allows...

Extra performance tips

Compile-time checks are not the only place where you can benefit from a performance enhancement at no cost. While in Chapter 1Common Performance Pitfallswe saw the common errors people write in Rust, we left the most advanced tips and tricks for this chapter.

Using closures to avoid runtime evaluation

Sometimes, it might seem natural to write code that does not perform as fast as expected. Many times, this is due to Rust doing some extra computations at runtime. An example of an unnecessary computation that someone could write is the following:

    let opt = Some(123);
let non_opt = opt.unwrap_or(some_complex_function());

I have intentionally made this example simply because a real...

Standard library collections

Rust's standard library has eight different collection types in the std::collections module. They are divided into sequences, maps, sets, and a binary heap that does not fit in any group. The most well known ones are arguably HashMap and Vec, but each of them has a use case, and you should know about them to use the proper one in each moment.

The official standard library documentation is really good, so you should check it thoroughly. In any case, though, I will introduce the types so that you can familiarize yourself with them. Let's start with sequences.

Sequences

The most-used dynamic sequence in Rust and in most languages is the vector, represented in Rust as Vec. You can add...

Summary

In this chapter, you learned how to use compile-time checks to your advantage. You learned how Rust's type system can help you create complex and safe behaviour without runtime overhead. You learned how to create state machines and how to make your code less error-prone.

You also learned about some extra performance enhancements that complement those of Chapter 1Common Performance Pitfalls. You learned about unstable sorting and map hashing, including perfect hash functions created at compile time, and how to create compile-time hash maps that will have no runtime overhead.

Finally, you learned about the collections in the standard library, how they are classified, and which type of collection you should use depending on the situation. You learned about sequences, maps, and sets, and how they can be adapted for your code.

One of the best Rust book I have ever read. This books is for you if you know Rut syntax and main principles of the language.Before reading this book I thought I'm strong beginner, but on 10th page I have understand that I'm still dont know Rust.

This book does not deliver on its promise. I was expecting deep-dive analysis of Rust code in specific situations. To my disappointment, performance aspects are covered only in the first 1/3 of whole book, And even there the topics covered are mostly trivial and well known to even non-advanced Rust users, lacking any serious analysis. Plus some basics of performance aspects generic to software development (tools, CPU architecture), not specific to Rust.The rest of the book is a random selection of various topics with very few loose references to performance (macros???).I'm not sure whom this book is for. Beginners will start somewhere else as this book does not introduce the language. Anyone who passed the introduction to Rust and got some minimal practics, will not find much interesting information here, either.

The first few chapters are ok, cover some rust specific topics like iterators, memory alignment, clippy etc.Then the parts about profiling and benchmarks are so high level they are pointless. The bench marking misses anything to do with issues relating to micro-benchmarking and compiler optimizations changing results. The later sections about threading and async could just be wikipedia articles.I get the feeling the author started with a lot of energy and then just wrote the second half of the book as quickly as possible.
