A full set of documentation and web-books is available at Learn Rust; the main resources in the form of books are listed below following their order of importance in the beginner learning path:

• Rust Book
• Rust By Example
• The Cargo Book

For learning and reviewing the basics of Rust I recommend the following videos; start with the first for a crash course and then take more time to repeat everything and learn in more depth with the second.

• Rust Programming (3h)
• Learn Rust Programming (13h)

Not yet reviewed:

• Rust 101 Crash Course (6h)

28.1 Beginner cheat-sheet

• Compilation and Cargo

Create hello.rs with the following and compile with rustc hello.rs:

// Comments are just like in C!
/* Multiline also work, but I don't like them!
   Write something useless here!
 */
fn main() {
    println!("Hello, world!");
}

Create a new project with cargo new hello-cargo; enter the folder and cargo run. Alternatively create the folder manually, enter it and cargo init.
