# IMixedRouteQuoterV1

Supports quoting the calculated amounts for exact input swaps. Is specialized for routes containing a mix of V1 and V2 liquidity.

For each pool also tells you the number of initialized ticks crossed and the sqrt price of the pool after the swap.

*These functions are not marked view because they rely on calling non-view functions and reverting to compute the result. They are also not gas efficient and should not be called on-chain.*

### Functions <a href="#functions" id="functions"></a>

#### quoteExactInput <a href="#quoteexactinput" id="quoteexactinput"></a>

Returns the amount out received for a given exact input swap without executing the swap

```solidity
function quoteExactInput(bytes memory path, uint256 amountIn)
    external
    returns (
        uint256 amountOut,
        uint160[] memory v2SqrtPriceX96AfterList,
        uint32[] memory v2InitializedTicksCrossedList,
        uint256 v2SwapGasEstimate
    );
```
