Hands-On Microservices with Rust

By: Denis Kolodin

Overview of this book

Microservice architecture is sweeping the world as the de facto pattern for building web-based applications. Rust is a language particularly well-suited for building microservices. It is a new system programming language that offers a practical and safe alternative to C. This book describes web development using the Rust programming language and will get you up and running with modern web frameworks and crates with examples of RESTful microservices creation. You will deep dive into Reactive programming, and asynchronous programming, and split your web application into a set of concurrent actors. The book provides several HTTP-handling examples with manageable memory allocations. You will walk through stateless high-performance microservices, which are ideally suitable for computation or caching tasks, and look at stateful microservices, which are filled with persistent data and database interactions. As we move along, you will learn how to use Rust macros to describe business or protocol entities of our application and compile them into native structs, which will be performed at full speed with the help of the server's CPU. Finally, you will be taken through examples of how to test and debug microservices and pack them into a tiny monolithic binary or put them into a container and deploy them to modern cloud platforms such as AWS.

Data Serialization and Deserialization with the Serde Crate

Microservices can either interact with clients or each other. To implement interaction, you have to choose a protocol and a format to send messages from one communication participant to another. There are many formats and RPC frameworks that simplify the interaction process. In this chapter, we'll discover features of the serde crate, which helps you to make structs serializable and deserializable and compatible with different formats, such as JSON, CBOR, MessagePack, and BSON.

The following topics will be covered in this chapter:

  • How to serialize and deserialize data
  • How to make custom types types serializable
  • Which serialization formats to choose and which to avoid
