In this lesson we discuss the bool type that represents either true or false.

Instructor: [00:00] Boolean types in Rust are just like they are in other languages as well. They either have the value true or they might have the value false depending on what the expression is resulting in. Also due to type inference, there is no need to attach the bool type annotation here.

[00:17] When we have values like this, we can create control structures like if, say, hello println!("Hello there"), or else we're going to say println!("Goodbye"). Running this code, we'll see that the program says Hello there.

[00:34] Pretty much everything in Rust is an expression. That means the value true or false can also result from expressions like 1 = 1, which is also true. Running this program again we see Hello there. On the other hand, if we create a expression that results in false, like 1 = 2 for example, we'll see that our program says Goodbye.
