This repository is for following along the official Rust book. I will be adding my notes and code snippets as I go through the book.

This link for the book: The Rust Programming Language

Notes

• Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.
• Rust is a statically typed language, which means that it must know the types of all variables at compile time.
• Rust is an ahead-of-time compiled language, which means you can compile a program and give the executable to someone else, and they can run it even without having Rust installed.
• Rust is a great choice when performance is important and you want to be sure that a program doesn’t have any undefined behavior.
• Rust is also great when you need to call code written in another language.
• Rust’s rich type system and ownership model guarantee memory safety and thread safety.
• Rust has a powerful macro system that allows metaprogramming.
• Rust has a minimal runtime, which means you can write programs with very small binaries.
• Rust has a great build system and a great package manager - Cargo.
• Rust has a lot of documentation and a great community!
• Rust is statically typed and compiled ahead of time.

Installation

• You can install Rust by running the following command in your terminal:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Cargo

• Cargo is Rust’s build system and package manager.

Hello, World!

• To create a new project, you can run the following command:

cargo new hello_world

• This will create a new directory called hello_world with the following structure:

hello_world
├── Cargo.toml
└── src
    └── main.rs

• The Cargo.toml file is the configuration file for the project.
• The src directory contains the source code for the project.
• The main.rs file contains the main function, which is the entry point for the program.
• To build and run the project, you can run the following command:

cd hello_world
cargo run

• This will compile and run the project, and you should see the output Hello, world!.
• You can also build the project without running it by running the following command:

cargo build

• This will compile the project and create an executable in the target/debug directory.
• You can run the executable by running the following command:

./target/debug/hello_world
