What happened so far?

This setup is the base for any other program with graphic output.

So far you have learned:

• how to install Rust and initialize a new Rust project with cargo.
• what a cargo manifest is, and how you can add dependencies.
• how to declare mutable and immutable variables and how to write functions.
• how to use two different types of loops and iterate over something.
• You got to know Rust's awesome error messages.
• You know what an enum is and can use match for control flow.
• You can look things up in the documentation.
• You made your first experience in handling errors and took the first step to write a multithreaded program.

Awesome!!!!
