Extended VRF Consumer Interface

Integrate a new, extended VRF Consumer interface on your contract.

interface IVRFConsumer {    
    function requestRandomness(
        bytes32 userProvidedSeed
    ) external returns (uint256);
    function getRequestById(
        uint256 nonce
    ) external view returns (RandomnessRequest memory);
    function getVRFPublicKey() external view returns (address);
}

struct RandomnessRequest {
    address requester;
    uint256 requestBlock;
    uint256 requestId;
    bytes32 userProvidedSeed;
    uint8 status;
    bytes32 randomNumber;
    bytes32 proof;
}

You can see a few new functions and a struct that you'll learn more about in the next sections.
