if
expressions
You use if
very similarly to how you would in other languages:
fn main() {
let mut x = 10;
if x % 2 == 0 {
x = x / 2;
} else {
x = 3 * x + 1;
}
}
In addition, you can use it as an expression. This does the same as above:
fn main() {
let mut x = 10;
x = if x % 2 == 0 {
x / 2
} else {
3 * x + 1
};
}
