manual_is_some

Source Code

What it does

Checks for manual implementations of is_some.

Example

fn main() {
    let foo: Option<i32> = Option::None;
    let _foo = match foo {
        Option::Some(_) => true,
        Option::None => false,
    };
}

Can be rewritten as:

fn main() {
    let foo: Option<i32> = Option::None;
    let _foo = foo.is_some();
}
