Overview of this book

Rust is a powerful language with a rare combination of safety, speed, and zero-cost abstractions. This Learning Path is filled with clear and simple explanations of its features along with real-world examples, demonstrating how you can build robust, scalable, and reliable programs. You’ll get started with an introduction to Rust data structures, algorithms, and essential language constructs. Next, you will understand how to store data using linked lists, arrays, stacks, and queues. You’ll also learn to implement sorting and searching algorithms, such as Brute Force algorithms, Greedy algorithms, Dynamic Programming, and Backtracking. As you progress, you’ll pick up on using Rust for systems programming, network programming, and the web. You’ll then move on to discover a variety of techniques, right from writing memory-safe code, to building idiomatic Rust libraries, and even advanced macros. By the end of this Learning Path, you’ll be able to implement Rust for enterprise projects, writing better tests and documentation, designing for performance, and creating idiomatic Rust code. This Learning Path includes content from the following Packt products: • Mastering Rust - Second Edition by Rahul Sharma and Vesa Kaihlavirta • Hands-On Data Structures and Algorithms with Rust by Claus Matzinger

Chapter 11. Logging

Logging is an important, yet overlooked, practice in the software development life cycle. It is often integrated as an afterthought on facing the consequences of latent invalid states and errors that accumulate over time in software systems. Any moderate sized project should have logging support from the initial days of development.

In this chapter, we'll get to know why setting up logging in an application is important, the need for a logging framework, how to approach logging, and what crates are available in the Rust ecosystem to enable programmers to leverage the power of logging in their applications.

In this chapter, we will cover the following topics:

  • What is logging and why do we need it?
  • The need for logging frameworks
  • Logging frameworks and their features
  • Exploring logging crates in Rust
