manual_ok

Source Code

What it does

Checks for manual implementation of ok method in match and if expressions.

Example

fn main() {
    let res_val: Result<i32> = Result::Err('err');
    let _a = match res_val {
        Result::Ok(x) => Option::Some(x),
        Result::Err(_) => Option::None,
    };
}

Can be replaced with:

    let res_val: Result<i32> = Result::Err('err');
    let _a = res_val.ok();
}
