this sdk provide offline-interfaces to calculate exchange token amount on iZiSwap.
with providing distribution of liquidity and limit order and currentPoint of pool,
you can call following interfaces to compute exchange amount of tokenX and tokenY
// swap from tokenY to tokenX
func SwapY2X(amount big.Int, highPt int, pool PoolInfo)
// swap from tokenX to tokenY
func SwapX2Y(amount big.Int, lowPt int, pool PoolInfo)
here when a pair is (tokenA, tokenB), if address(tokenA).LowerCase() < address(tokenB).LowerCase() then, tokenA is tokenX, tokenB is tokenY, otherwise, tokenB is tokenX, tokenA is tokenY.
for more detail of usage, you can refer to example.go.txt
