1. PartialEq PartialOrd trait

让你可以自由地定义=和不=
让你可以自由地定义>和<

1. 一个标准的单元测试应该这样写

   #[cfg(test)]
   pub mod test{
    use crate::heap::test::Node;
    #[test]
    pub fn test_partial_eq(){
        let node_1=Node{
            value:2,
            pos:3,
        };
        let node_2=Node{
            value:3,
            pos:4,
        };
        assert!(node_1!=node_2);
    }
   }
