structure Boolean in Rust 1.55

Boolean in Rust represents truth values, which can either be true or false. Boolean values are represented using the bool type in Rust, and they play a very important role in programming as they help in the evaluation of logical expressions.

Here are some examples of how to use boolean in Rust:

1. To declare a variable of boolean type:

let x: bool = true;
let y: bool = false;

2. To declare a function that returns a boolean value:

fn is_even(num: i32) -> bool {
    if num % 2 == 0 {
        return true;
    } else {
        return false;
    }
}

3. To use boolean values in control flow statements:

let num = 5;
if num < 10 {
    println!("{} is less than 10", num);
} else {
    println!("{} is greater than or equal to 10", num);
}

4. To use boolean values in logical expressions:

let a = true;
let b = false;
println!("a AND b is {}", a && b);
println!("a OR b is {}", a || b);
println!("NOT a is {}", !a);

In these examples, the && operator represents logical and, || represents logical or, and ! represents logical not.

Using boolean values in Rust is simple and intuitive, and they can help make your programs more efficient and effective.
