我想为全局变量赋值,但它一直有编译器错误:

static mut NameArr: [&'static str; 20] = ["\0"; 20];

fn main() {

  unsafe {
    static mut S1 :String = "".to_string();

    S1.push('\0');

    NameArr[0] = S1.as_slice();
  }
}

错误:

a.rs:7:29: 7:43 error: mutable statics are not allowed to have destructors
a.rs:7     static mut S1 :String = "".to_string();
                                   ^~~~~~~~~~~~~~
