Logical Operators: And (&&) in Rust

Sometimes you will need to test more than one thing at a time. The logical and operator (&&) returns true if and only if both conditions to the left and right of it are true. For example:

10 == 10 && 7 < 10 // Evaluates to true

We have two conditions separated by && operator:

• 10 == 10, which evaluates to true
• 7 < 10, which evaluates to true

An example inside an if statement:

let x = 10;
if x != 7 && 12 < x { // Evaluates to false
    println!("This is true!");
}

Inside the if, we have two conditions separated by && operator:

• x != 7, equivalent to 10 != 7, which evaluates to true
• 12 < x, equivalent to 12 < 10, which evaluates to false
