Functions

func DisableLog

func DisableLog()

DisableLog disables all library log output. Logging output is disabled by default until either UseLogger or SetLogWriter are called.

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 BlockConnected

type BlockConnected wtxmgr.BlockMeta

BlockConnected is a notification for a newly-attached block to the best chain.

type BlockDisconnected

type BlockDisconnected wtxmgr.BlockMeta

BlockDisconnected is a notifcation that the block described by the BlockStamp was reorganized out of the best chain.

type ClientConnected

type ClientConnected struct{}

ClientConnected is a notification for when a client connection is opened or reestablished to the chain server.

type RPCClient

type RPCClient struct {
	*btcrpcclient.Client
	// contains filtered or unexported fields
}

RPCClient represents a persistent client connection to a bitcoin RPC server for information regarding the current best block chain.

func NewRPCClient

func NewRPCClient(chainParams *chaincfg.Params, connect, user, pass string, certs []byte,
	disableTLS bool, reconnectAttempts int) (*RPCClient, error)

NewRPCClient creates a client connection to the server described by the connect string. If disableTLS is false, the remote RPC certificate must be provided in the certs slice. The connection is not established immediately, but must be done using the Start method. If the remote server does not operate on the same bitcoin network as described by the passed chain parameters, the connection will be disconnected.

func (*RPCClient) BlockStamp

func (c *RPCClient) BlockStamp() (*waddrmgr.BlockStamp, error)

BlockStamp returns the latest block notified by the client, or an error if the client has been shut down.

func (*RPCClient) Notifications

func (c *RPCClient) Notifications() <-chan interface{}

Notifications returns a channel of parsed notifications sent by the remote bitcoin RPC server. This channel must be continually read or the process may abort for running out memory, as unread notifications are queued for later reads.

func (*RPCClient) POSTClient

func (c *RPCClient) POSTClient() (*btcrpcclient.Client, error)

POSTClient creates the equivalent HTTP POST btcrpcclient.Client.

func (*RPCClient) Start

func (c *RPCClient) Start() error

Start attempts to establish a client connection with the remote server. If successful, handler goroutines are started to process notifications sent by the server. After a limited number of connection attempts, this function gives up, and therefore will not block forever waiting for the connection to be established to a server that may not exist.

func (*RPCClient) Stop

func (c *RPCClient) Stop()

Stop disconnects the client and signals the shutdown of all goroutines started by Start.

func (*RPCClient) WaitForShutdown

func (c *RPCClient) WaitForShutdown()

WaitForShutdown blocks until both the client has finished disconnecting and all handlers have exited.

type RelevantTx

type RelevantTx struct {
	TxRecord *wtxmgr.TxRecord
	Block    *wtxmgr.BlockMeta // nil if unmined
}

RelevantTx is a notification for a transaction which spends wallet inputs or pays to a watched address.

type RescanFinished

type RescanFinished struct {
	Hash   *chainhash.Hash
	Height int32
	Time   time.Time
}

RescanFinished is a notification that a previous rescan request has finished.

type RescanProgress

type RescanProgress struct {
	Hash   *chainhash.Hash
	Height int32
	Time   time.Time
}

RescanProgress is a notification describing the current status of an in-progress rescan.
