Rust Programming Cookbook

How to do it...

Let's go through the following steps:

1. Use cargo to create a new project, cargo new traits --lib, or clone it from this book's GitHub repository (https://github.com/PacktPublishing/Rust-Programming-Cookbook). Use Visual Studio Code and Terminal to open the project's directory.
2. Implement a simple configuration management service. To do that, we need some structs to work with:

use std::io::{Read, Write};////// Configuration for our application/// pub struct Config {    values: Vec<(String, String)>}////// A service for managing a configuration/// pub struct KeyValueConfigService {}

Additionally, some constructors make them easier to use:

// Implsimpl Config {    pub fn new(values: Vec<(String, String)>) -> Config { Config { values: ...
