Small pattern that made my code much cleaner

This is a really simple silly thing I just realized, but I noticed I have a lot code that looks something like this:

    
fn foo() -> Result&lt;(), Error> {
    // do something
}

fn bar() -> Option&lt;()> {
    let Ok(f) = foo() else {
        return None;
    };
}

I hated that if-statement. I realized today that I could simplify to:

    
fn bar() -> Option&lt;()> {
    let f = foo().ok()?;
}

And that cleaned up my code a lot. It's a tiny thing, but when it's okay to discard the error from the result, makes such a big difference when you have a lot of them!
