Functions

func MigrateChannelIDIndex

func MigrateChannelIDIndex(tx kvdb.RwTx) error

MigrateChannelIDIndex adds a new channel ID index to the tower client db. This index is a mapping from db-assigned ID (a uint64 encoded using BigSize encoding) to real channel ID (32 bytes). This mapping will allow us to persist channel pointers with fewer bytes in the future.

func UseLogger

func UseLogger(logger btclog.Logger)

UseLogger uses a specified 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 (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.
