pragma solidity ^0.6.0;

interface IPeople {

    struct Student {
        uint status;

    }
      function getStudent(address _productAddr) external view returns (Student memory) ;
}

pragma solidity >=0.6.0;

contract Want  {

IPeople public _people =IPeople(0xCcCCccccCCCCcCCCCCCcCcCccCcCCCcCcccccccC) ;   

function hi()external {
    address _pAddr = 0xbBbBBBBbbBBBbbbBbbBbbbbBBbBbbbbBbBbbBBbB;
    IPeople.Student memory _p = _people.getStudent(_pAddr);

}

}

请教一下代码里面的IPeople.Student 不能这样用吗，合约部署没问题，但是函数调用会失败
