Control Flow with If Expressions

Snippet

Control Flow with If Expressions

In Rust, 'if' is an expression, not just a statement. This means it returns a value that can be assigned to a variable, provided all branches return the same type.

snippet.rs
rust
fn main() {
    let number = 7;
    let condition = if number < 10 {
        true
    } else {
        false
    };
    println!("Condition is {condition}");
}

Breakdown

let condition = if number < 10 {

Starts an assignment where the value depends on the if-condition result.

true

The value returned if the condition is met (no semicolon here).

} else { false };

The fallback value returned if the condition is false.
