function computeAddress(address factory, PoolKey memory key) internal pure returns (address pool) {
    require(key.token0 < key.token1);
    pool = address(
        uint256(
            keccak256(
                abi.encodePacked(
                    hex'ff',
                    factory,
                    keccak256(abi.encode(key.token0, key.token1, key.fee)),
                    POOL_INIT_CODE_HASH
                )
            )
        )
    );
}

合约里面 uint256转address可以用address(uint256)，但需要address转成uint256又改怎么写呢？ 如果是在js里面互转是用什么方法？

address(57896044618658097711785492504451499836465512412780742056059170478185526900045)

在合约里面转address得到结果是0x12D6867FA648d269835cf69B49F125147754B54d 如果使用

uint256(uint160(0x12D6867FA648d269835cf69B49F125147754B54d))

得到的却是107545909830520079960460036330378474228962080077
