In this chapter, we learned about the importance of logging in software development and the ways of approaching it, including what characteristics to look for when choosing a logging framework. We also got to know about unstructured and structured logging, their pros and cons, and explored the available crates in the Rust ecosystem to integrate logging into our applications.

The next chapter will be about network programming, where we will explore the built-in facilities and crates that Rust provides to create efficient applications that communicate with one another.
