| value | uint256 | The amount that can be spent of token |
| deadline | uint256 | A timestamp, the current blocktime must be less than or equal to this timestamp |

selfPermitAllowedIfNecessary(token: address, nonce: uint256, expiry: uint256, v: uint8, r: bytes32, s: bytes32)
payable
Permits this contract to spend the sender's tokens for permit signatures that have the `allowed` parameter
dev: The `owner` is always msg.sender and the `spender` is always address(this) Can be used instead of #selfPermitAllowed to prevent calls from failing due to a frontrun of a call to #selfPermitAllowed.

| nonce | uint256 | The current nonce of the owner |
| expiry | uint256 | The timestamp at which the permit is no longer valid |

uniswapV3SwapCallback(amount0Delta: int256, amount1Delta: int256, _data: bytes)
nonpayable
Called to `msg.sender` after executing a swap via IUniswapV3Pool#swap.
dev: In the implementation you must pay the pool tokens owed for the swap. The caller of this method must be checked to be a UniswapV3Pool deployed by the canonical UniswapV3Factory. amount0Delta and amount1Delta can both be 0 if no tokens were swapped.
Parameters
| Name | Type | Description |
|---|---|---|
| amount0Delta | int256 | The amount of token0 that was sent (negative) or must be received (positive) by the pool by the end of the swap. If positive, the callback must send that amount of token0 to the pool. |
| amount1Delta | int256 | The amount of token1 that was sent (negative) or must be received (positive) by the pool by the end of the swap. If positive, the callback must send that amount of token1 to the pool. |
| _data | bytes |
