Slot0

Git Source - Generated with forge doc

Slot0 is a packed version of solidity structure. Using the packaged version saves gas by not storing the structure fields in memory slots. Layout: 24 bits empty | 24 bits lpFee | 12 bits protocolFee 1->0 | 12 bits protocolFee 0->1 | 24 bits tick | 160 bits sqrtPriceX96 Fields in the direction from the least significant bit: The current price uint160 sqrtPriceX96; The current tick int24 tick; Protocol fee, expressed in hundredths of a bip, upper 12 bits are for 1->0, and the lower 12 are for 0->1 the maximum is 1000 - meaning the maximum protocol fee is 0.1% the protocolFee is taken from the input first, then the lpFee is taken from the remaining input uint24 protocolFee; The current LP fee of the pool. If the pool is dynamic, this does not include the dynamic fee flag. uint24 lpFee;

type Slot0 is bytes32;
