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. Credit to Uniswap Labs under GPL-2.0-or-later license: https://github.com/Uniswap/v3-periphery

algebraSwapCallback
Selector: 0x2c8958f6
Called to `msg.sender` after executing a swap via IAlgebraPool#swap.
Developer note: In the implementation you must pay the pool tokens owed for the swap. The caller of this method must be checked to be a AlgebraPool deployed by the canonical AlgebraFactory. amount0Delta and amount1Delta can both be 0 if no tokens were swapped.
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.
