P.FUD.02 Don't Use return for return value

[Description]

In such that function would automatically return the value of last expression in Rust, it is not required to use return explicitly.

Only when it is necessary to return a value in procedure of function, should use return explicitly.

[Bad Case]

#![allow(unused)]
fn main() {
fn foo(x: usize) -> usize {
    if x < 42 {
        return x;
    }
    return x + 1; // Not Good
}
}

[Good Case]

#![allow(unused)]
fn main() {
fn foo(x: usize) -> usize {
    if x < 42 {
        return x;
    }
    x + 1 // Good
}
}
