Mozilla’s Rust is gaining much attention with amazing features and a powerful library. This book will take you through varied recipes to teach you how to leverage the Standard library to implement efficient solutions. The book begins with a brief look at the basic modules of the Standard library and collections. From here, the recipes will cover packages that support file/directory handling and interaction through parsing. You will learn about packages related to advanced data structures, error handling, and networking. You will also learn to work with futures and experimental nightly features. The book also covers the most relevant external crates in Rust. By the end of the book, you will be proficient at using the Rust Standard library.

  1. In the folder src/bin, create a file called
  2. Add the following code, and run it with cargo run --bin vecdeque:
1   use std::collections::VecDeque;
3 fn main() {
4 // A VecDeque is best thought of as a
5 // First-In-First-Out (FIFO) queue
7 // Usually, you will use it to push_back data
8 // and then remove it again with pop_front
9 let mut orders = VecDeque::new();
10 println!("A guest ordered oysters!");
11 orders.push_back("oysters");
13 println!("A guest ordered fish and chips!");
14 orders.push_back("fish and chips");
16 let prepared = orders.pop_front();
17 if let Some(prepared) = prepared {
18 println!("{} are ready", prepared);

21 println!("A guest ordered mozarella sticks!");
22 orders.push_back("mozarella sticks");
24 let prepared = orders.pop_front();
