Types

type FRet

type FRet uint

FRet find the return value of the tx

const (
	// NotFound ...
	NotFound FRet = iota
	// FoundPending ...
	FoundPending
	// FoundChain ...
	FoundChain
)

type Iterator

type Iterator struct {
	// contains filtered or unexported fields
}

Iterator This is the iterator

func (*Iterator) Next

func (iter *Iterator) Next() (*tx.Tx, bool)

Next next the tx

	// contains filtered or unexported fields
}

SortedTxMap is a red black tree of tx.

func NewSortedTxMap

func NewSortedTxMap() *SortedTxMap

NewSortedTxMap returns a new SortedTxMap instance.

func (*SortedTxMap) Add

func (st *SortedTxMap) Add(tx *tx.Tx)
