Mastering Go - Second Edition

By: Mihalis Tsoukalos

Overview of this book

Often referred to (incorrectly) as Golang, Go is the high-performance systems language of the future. Mastering Go, Second Edition helps you become a productive expert Go programmer, building and improving on the groundbreaking first edition. Mastering Go, Second Edition shows how to put Go to work on real production systems. For programmers who already know the Go language basics, this book provides examples, patterns, and clear explanations to help you deeply understand Go’s capabilities and apply them in your programming work. The book covers the nuances of Go, with in-depth guides on types and structures, packages, concurrency, network programming, compiler design, optimization, and more. Each chapter ends with exercises and resources to fully embed your new knowledge. This second edition includes a completely new chapter on machine learning in Go, guiding you from the foundation statistics techniques through simple regression and clustering to classification, neural networks, and anomaly detection. Other chapters are expanded to cover using Go with Docker and Kubernetes, Git, WebAssembly, JSON, and more. If you take the Go programming language seriously, the second edition of this book is an essential guide on expert techniques.

Comparing Go and Rust concurrency models

Rust is a very popular systems programming language that also supports concurrent programming. Briefly speaking, some characteristics of Rust and the Rust concurrency model are as follows:

  • Rust threads are UNIX threads, which means that they are heavy but can do many things.
  • Rust supports both message-passing and shared-state concurrency like Go does with channels, mutexes, and shared variables.
  • Based on its strict type and ownership system, Rust provides a safe thread mutable state. The rules are enforced by the Rust compiler.
  • There are Rust structures that allow you to share state.
  • If a thread starts misbehaving, the system will not crash. This situation can be handled and controlled.
  • The Rust programming language is under constant development, which might discourage some people from using it as they might need to make changes to their...
