    regexm::regexm!(match text1 {
        r"^\d{4}$" => println!("y"),
        r"^\d{4}-\d{2}$" => println!("y-m"),
        // block
        r"^\d{4}-\d{2}-\d{2}$" => {
            let y_m_d = "y-m-d";
            println!("{}", y_m_d);
        }
        _ => println!("default"),
    });
}

Output:

y-m-d

fn main() {
    let text2 = "foo";
    let foo = regexm::regexm!(match text2 {
        r"^\d{4}-\d{2}-\d{2}$" => "ymd",
        r"^\d{4}-\d{2}$" => "ym",
        // block
        r"^\d{4}-\d{2}-\d{2}$" => {
            let ymd = "ymd";
            ymd
        }
        _ => "default",
    });
    println!("{}", foo);
}

Output:

default
