QuoterV2

Allows getting the expected amount out or amount in for a given swap without executing the swap 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.

Functions

  function constructor(
  ) public

uniswapV3SwapCallback

  function uniswapV3SwapCallback(
    int256 amount0Delta,
    int256 amount1Delta,
    bytes data
  ) external view override

Called to msg.sender after executing a swap via IRamsesV3Pool#swap. In the implementation you must pay the pool tokens owed for the swap. The caller of this method must be checked to be a RamsesV3Pool deployed by the canonical RamsesV3Factory. 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	Any data passed through by the caller via the IRamsesV3PoolActions#swap call.
