Solidity - Immutable

 

Immutable variables are like constants. Values of immutable variables can be set inside the constructor but cannot be modified afterwards.

불변 변수는 상수와 같습니다. 불변 변수의 값은 생성자 내부에서 설정할 수 있지만 이후에는 수정할 수 없습니다.

contract Immutable {
    // coding convention to uppercase constant variables
    // 상수변수의 코딩 컨벤션은 대문자다.
    
    address public immutable MY_ADDRESS;
    uint public immutable MY_UINT;

    constructor(uint _myUint) {
        MY_ADDRESS = msg.sender;
        MY_UINT = _myUint;
    }
}
