Functions

func CheckMerkleBlock

func CheckMerkleBlock(m msg.MerkleBlock) ([]*common.Uint256, error)

take in a merkle block, parse through it, and return txids indicated If there's any problem return an error. Checks self-consistency only. doing it with a stack instead of recursion. Because... OK I don't know why I'm just not in to recursion OK?

func NewMerkleBlock

func NewMerkleBlock(block *types.Block, filter *Filter) (*msg.MerkleBlock, []uint32)

NewMerkleBlock returns a new *MerkleBlock

Types

	// contains filtered or unexported fields
}

func New

func New(newFilter func(filterType TxFilterType) TxFilter) *Filter

func (*Filter) Add

func (*Filter) Match

func (f *Filter) Match(tx *types.Transaction) bool

type TxFilter

type TxFilter interface {
	// Load loads the transaction filter.
	Load(filter []byte) error

	// Add adds new data into filter.
	Add(data []byte) error

	// Match returns if a transaction matches the filter.
	Match(tx *types.Transaction) bool
