ChainlinkContructorArgs

Because of the Stack too deep error, we combine some constructor arguments into a single stuct

struct ChainlinkContructorArgs {
  address vrfCoordinator;
  bytes32 keyHash;
  uint16 minimumRequestConfirmations;
  uint32 callbackGasLimit;
}

subscriptionID

uint64 subscriptionID

callbackGasLimit

uint32 callbackGasLimit

Chainlink VRF V2 gas limit to call fulfillRandomWords() with.

vrfCoordinator

contract VRFCoordinatorV2Interface vrfCoordinator

Chainlink VRF V2 coordinator.
