Functions

func UseLogger

func UseLogger(logger btclog.Logger)

UseLogger uses a specified Logger to output package logging info. This should be used in preference to SetLogWriter if the caller is also using btclog.

Types

type NodeConn

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

NodeConn handles all the connection logic to a remote LND node using LNC.

func NewNodeConn

func NewNodeConn(session *Session, store Store) (*NodeConn, error)

NewNodeConn creates a new NodeConn instance.

func (*NodeConn) Client

func (n *NodeConn) Client() (lnrpc.LightningClient, error)

Client returns the gRPC client to the remote node.

func (*NodeConn) CloseConn

func (n *NodeConn) CloseConn() error

CloseConn closes the connection with the remote node.

func (*NodeConn) CtxFunc

func (n *NodeConn) CtxFunc() context.Context

CtxFunc returns the context that needs to be used whenever the internal Client is used.

func (*NodeConn) Stop

func (n *NodeConn) Stop() error

Stop closes the connection with the remote node if it is open.

type Session

type Session struct {
	// PassphraseWords is the list of words the PassphraseEntropy is derived
	// from.
	PassphraseWords string

	// PassphraseEntropy is the entropy. This field identifies the session.
	PassphraseEntropy []byte

	// RemoteStaticPubKey is the public key of the remote peer.
	RemoteStaticPubKey *btcec.PublicKey

	// LocalStaticPrivKey is the private key of the local peer.
	LocalStaticPrivKey *btcec.PrivateKey

	// MailboxAddr is the address of the mailbox server.
	MailboxAddr string

	// CreatedAt is the time the session was added to the database.
	CreatedAt time.Time

	// Expiry is the time the session will expire.
	Expiry *time.Time

	// DevServer signals if we need to skip the verification of the server's
	// tls certificate.
	DevServer bool
}

Session contains all the information needed for an LNC connection.

func NewSession

func NewSession(passphrase, mailboxAddr string, devServer bool) (*Session,
	error)

NewSession creates a new non-initialized session.

type Store

type Store interface {
	// AddSession adds a record for a new session in the database.
	AddSession(ctx context.Context, session *Session) error

	// GetSession retrieves the session record matching the passphrase
	// entropy.
	GetSession(ctx context.Context,
		passphraseEntropy []byte) (*Session, error)

	// SetRemotePubKey sets the remote public key for a session.
	SetRemotePubKey(ctx context.Context, passphraseEntropy,
		remotePubKey []byte) error

	// SetExpiry sets the expiry time for a session.
	SetExpiry(ctx context.Context, passphraseEntroy []byte,
		expiry time.Time) error
}

Store represents access to a persistent session store.
