Functions

func MigrateChanID

func MigrateChanID(tx kvdb.RwTx) error

MigrateChanID populates the ChannelID index by using the set of outpoints retrieved from the outpoint bucket.

func UseLogger

func UseLogger(logger btclog.Logger)

UseLogger uses a specific Logger to output package logging info.

Types

type ChannelID

type ChannelID [32]byte

ChannelID is a series of 32-bytes that uniquely identifies all channels within the network. The ChannelID is computed using the outpoint of the funding transaction (the txid, and output index). Given a funding output the ChannelID can be calculated by XOR'ing the big-endian serialization of the txid and the big-endian serialization of the output index, truncated to 2 bytes.

func NewChanIDFromOutPoint

func NewChanIDFromOutPoint(op *wire.OutPoint) ChannelID

NewChanIDFromOutPoint converts a target OutPoint into a ChannelID that is usable within the network. In order to convert the OutPoint into a ChannelID, we XOR the lower 2-bytes of the txid within the OutPoint with the big-endian serialization of the Index of the OutPoint, truncated to 2-bytes.

func (ChannelID) String

func (c ChannelID) String() string

String returns the string representation of the ChannelID. This is just the hex string encoding of the ChannelID itself.
