Types

type FeeAmount

type FeeAmount uint64

The default factory enabled fee amounts, denominated in hundredths of bips.

const (
	FeeLowest FeeAmount = 100
	FeeLow    FeeAmount = 500
	FeeMedium FeeAmount = 3000
	FeeHigh   FeeAmount = 10000

	FeeMax FeeAmount = 1000000
)

type FeePair

type FeePair struct {
	Fee0 FeeAmount
	Fee1 FeeAmount
}
