Sketchbook for Rust Programming Language Book

This repository contains sketches of code I used while following along a modified version of the Rust Programming Language Book.

This version contains an interactive component made of quizzes to aid in practicing the concepts in the book.

Structure of the repository

Each chapter, and most of the time each subchapter of the book, will have its own folder, appropriately identified; its contents are the result of me following the book along.

Some chapters, like 2, 12, and 20, leave to the reader the task of implementing small practical projects, which I will try to do in their entirety.

minigrep (Chapter 12)

Chapter 12 presents an extremely simple project for a grep that does not recurse directories, and only searches the file specified as argument.

• Run cargo test to verify the executable respects the case-insensitiveness flag
• Run cargo run -- to poem.txt to test it on the book's example file
• Run cargo run 2> error.txt to see that the executable prints errors to STDERR correctly

Mini Rust Web Server (Chapter 20)

In Chapter 20, a very simple web server running on localhost is built. It is capable of serving concurrent requests, using a thread pool. The Rust async book does the same with async/await.

The below cargo commands assume pwd is that of chapter 20's project.

Running the server

• Run cargo run to start the server, and then:
  • Access 127.0.0.1:7878 in a browser for the regular HTML being served
  • Access 127.0.0.1:7878/{anything} for the HTML served in case of error
  • Access 127.0.0.1:7878/sleep for a page equal to the first, but only served after a 5 second delay

To check the server thread pool's concurrent behavior, duplicate a 127.0.0.1:7878/sleep tab while checking STDOUT.

Tests and documentation

• Run cargo test to test the concurrent behavior of ThreadPool. There are currently two integration tests, that combine creating some files and std::thread::sleep to check crate::ThreadPool behaves correctly.

• Run cargo doc --open to read the package's documentation, with notes reflecting the content in chapter 20, and some of the author's own.
