Functions
Decodes the Q64.96-encoded sqrt price from Uniswap into an intuitive price
Scales the input sqrt_price by scale factor to enable limited slippage in Uniswap swaps It is necessary to first identify the direction of the swap as Uniswap depends on that for slippage calculation, use get_uniswap_tokens() to receive an ordered tuple (token0: Address, token1: Address)
Computes the sqrt price of a pool given token_1’s liquidity and token_0’s liquidity When used as the sqrt price limit, this calculates the maximum price that a swap is allowed to push the pool to by changing the underlying liquidity without having the tx revert Attempts to encode the result as a Q64.96 by copying the javascript implementation (see https://en.wikipedia.org/wiki/Q_(number_format), a 160 bit number v represented in Q64.96 would be equal to (v/2^96))
Encodes a given spot price as a Q64.96 sqrt price which Uniswap expects, used in limiting slippage See uniswap_sqrt_price_from_amounts for the general case
