QuoterV2
Provides quotes for swaps Allows getting the expected amount out or amount in for a given swap without executing the swap Developer note: These functions are not gas efficient and should not be called on chain. Instead, optimistically execute the swap and check the amounts in the callback.

algebraSwapCallback
algebraSwapCallback(int256,int256,bytes) view external
Called to `msg.sender` after executing a swap via IAlgebraPool#swap.
| 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. |
