It doesn't work when i use shadowing

[maozx]

it work well:

let mut a = String::from("hello");
let a = a.len();
match a {
    1 => println!("1"),
    2 => println!("2"),
    _ => println!("other"),
}

but it doesn't work:

let mut number = String::new();
io::stdin().read_line(&mut number).expect("cannot get your write number.");

let numer: i32 = number.trim().parse().expect("invalid number");
match number {
    1 => guess_number::game(),
    2 => test01::test01(),
    _ => {
        println!("mode number not support.")
    }
}

error is:

@maozx

let numer: i32 = number.trim().parse().expect("invalid number");
