beforeInitialize = trueRuns custom logic before liquidity is added, and can block deposits.
beforeAddLiquidity = trueRuns custom logic after liquidity is added.
afterAddLiquidity = trueRuns custom logic after liquidity is withdrawn.
afterRemoveLiquidity = trueRuns custom logic before every swap. It can change the fee or block the trade.
beforeSwap = trueRuns custom logic after every swap.
afterSwap = trueRuns custom logic before tokens are donated to the pool's liquidity providers.
beforeDonate = trueCan change how much a trader pays or receives before the swap executes.
beforeSwapReturnDelta = trueCan take or add tokens to a trade's output after the swap executes.
afterSwapReturnDelta = true
These describe when the hook is called, not everything it does once called. Not used: afterInitialize, beforeRemoveLiquidity, afterDonate, afterAddLiquidityReturnDelta, afterRemoveLiquidityReturnDelta.
