Functions

func NewAddressFromPubKeyStr

func NewAddressFromPubKeyStr(netParam *chaincfg.Params, pubKeyHex string, addressType AddressType) (string, error)

func NewAddressWithPubKey

func NewAddressWithPubKey(netParam *chaincfg.Params, pubKey *btcec.PublicKey, compressed bool,
	addrType AddressType) (btcutil.Address, error)

NewAddressWithPubKey returns a new address based on the passed account, public key, and whether or not the public key should be compressed.

Types

type AddressType

type AddressType uint8

AddressType represents the various address types waddrmgr is currently able to generate, and maintain.

NOTE: These MUST be stable as they're used for scope address schema recognition within the database.

const (
	// PubKeyHash is a regular p2pkh address.
	PubKeyHash AddressType = iota

	// Script reprints a raw script address.
	Script

	// RawPubKey is just raw public key to be used within scripts, This
	// type indicates that a scoped manager with this address type
	// shouldn't be consulted during historical rescans.
	RawPubKey

	// NestedWitnessPubKey represents a p2wkh output nested within a p2sh
	// output. Using this address type, the wallet can receive funds from
	// other wallet's which don't yet recognize the new segwit standard
	// output types. Receiving funds to this address maintains the
	// scalability, and malleability fixes due to segwit in a backwards
	// compatible manner.
	NestedWitnessPubKey

	// WitnessPubKey represents a p2wkh (pay-to-witness-key-hash) address
	// type.
	WitnessPubKey

	// WitnessScript represents a p2wsh (pay-to-witness-script-hash) address
	// type.
	WitnessScript

	// TaprootPubKey represents a p2tr (pay-to-taproot) address type that
	// uses BIP-0086 (for the derivation path and for calculating the tap
	// root hash/tweak).
	TaprootPubKey

	// TaprootScript represents a p2tr (pay-to-taproot) address type that
	// commits to a script and not just a single key.
	TaprootScript
)

type FileHeader

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

FileHeader represents the mempool file header

func (FileHeader) GetTxCount

GetFileHeader returns a the mempool file header

func (Mempool) GetMapDeltas

func (mempool Mempool) GetMapDeltas() []byte

GetMapDeltas returns a byte slice of not parsed mapDelta entries

func (Mempool) GetMempoolEntries

func (mempool Mempool) GetMempoolEntries() []MempoolEntry

GetFeeDelta returns feeDelta of the entry

func (MempoolEntry) GetFirstSeen

func (entry MempoolEntry) GetFirstSeen() int64

GetFirstSeen returns the firstSeen time of the entry as timestamp

func (MempoolEntry) Info

func (entry MempoolEntry) Info() string

Info returns a string with information for a given MempoolEntry

func (MempoolEntry) IsSegWit
