一个简单的crate，用于防止某些变量被内存篡改工具修改。

用法

   protected_integer = "0.1"
   

2. 在项目中使用此crate

   use protected_integer::{ProtectedInteger, State};
   
   let mut my_number = ProtectedInteger::new(114514); // initialize this variable
   
   // Check and get the value
   match my_number.get() {
       State::Untampered(num) => {
           println!("The variable has not been tampered with");
       }
       State::Tampered(num) => {
           println!("The variable was tampered with, but the backup variable was not");
           println!("The restored value is {}", num);
       }
   }
   
   // change the value
   my_number.set(1919810);
