Example

#![warn(clippy::implicit_saturating_add)]

fn main() {
    let mut i: u32 = 3;

    if i != MAX {
        i += 1;
    }
    println!("{}", i);
}

Could be written as:

#![warn(clippy::implicit_saturating_add)]

fn main() {
    let mut i: u32 = 3;

    if i != MAX {
        i = i.saturating_add(1);
    }
    println!("{}", i);
}

I'm assume you mean if i !=MAX { i += 1 } to i = i.saturating_add(1).
