Functions

func FindGoodTradePath

func FindGoodTradePath(
	maxPathLen uint,
	poolPairStates map[string]*jsonresult.Pdexv3PoolPairState,
	tokenIDStrSource string,
	tokenIDStrDest string,
	originalSellAmount uint64,
) ([]*jsonresult.Pdexv3PoolPair, []string, uint64)

FindGoodTradePath attempts to find a good enough trading path for the given trading pair, selling amount, and pool pairs.

func TradePathFromState

func TradePathFromState(
	sellToken common.Hash,
	tradePath []string,
	pairs map[string]*jsonresult.Pdexv3PoolPairState,
) (
	[]*jsonresult.Pdexv3PoolPair, []v2.OrderBookIterator, []byte, error,
)

Types

type Node
