func (*Messager) AckMsgQueue ¶

func (m *Messager) AckMsgQueue(cid ctype.CidType, ack, nack uint64) error

ACK a message in a channel queue.

func (*Messager) DisableMsgQueue ¶

func (m *Messager) DisableMsgQueue(peer ctype.Addr) error

Disable message queue processing for this peer address.

func (*Messager) EnableMsgQueue ¶

func (m *Messager) EnableMsgQueue(peer ctype.Addr) error

Enable message queue processing for this peer address.

func (*Messager) ForwardCelerMsg ¶

func (m *Messager) ForwardCelerMsg(peerTo ctype.Addr, msg *rpc.CelerMsg) error

func (*Messager) ForwardCondPayRequest ¶

func (m *Messager) ForwardCondPayRequest(
	payBytes []byte, note *any.Any, delegable bool, xnet *rpc.CrossNetPay, logEntry *pem.PayEventMessage) (ctype.Addr, error)

func (*Messager) ForwardCondPayRequestMsg ¶

func (m *Messager) ForwardCondPayRequestMsg(frame *common.MsgFrame) error

func (*Messager) ForwardPaySettleProofMsg ¶

func (m *Messager) ForwardPaySettleProofMsg(frame *common.MsgFrame) error

func (*Messager) ForwardPaySettleRequestMsg ¶

func (m *Messager) ForwardPaySettleRequestMsg(frame *common.MsgFrame) error

func (*Messager) GetMsgQueue ¶

func (m *Messager) GetMsgQueue(cid ctype.CidType, seqnum uint64) (*rpc.CelerMsg, bool)

Get a message from a channel queue.

func (*Messager) IsDirectPay ¶

func (m *Messager) IsDirectPay(pay *entity.ConditionalPay, peer ctype.Addr, dstNetId uint64) bool

Is this a direct payment from me to this peer? The peer is an optional parameter, if it is not given (an empty string), the next hop peer is looked up. For now only consider unconditional payments where I am the source and the destination is my next hop peer. This is typical of fee (client to OSP) and prize (OSP to client) payments in centralized games.

func (*Messager) ResendMsgQueue ¶

func (m *Messager) ResendMsgQueue(cid ctype.CidType, seqnum uint64) error

Resend a message in a channel queue.

func (*Messager) SendCondPayRequest ¶

func (m *Messager) SendCondPayRequest(payBytes []byte, note *any.Any, xnet *rpc.CrossNetPay, logEntry *pem.PayEventMessage) error

func (*Messager) SendOnePaySettleProof ¶

func (m *Messager) SendOnePaySettleProof(
	payID ctype.PayIDType,
	reason rpc.PaymentSettleReason,
	logEntry *pem.PayEventMessage) error

func (*Messager) SendOnePaySettleRequest ¶

func (m *Messager) SendOnePaySettleRequest(
	pay *entity.ConditionalPay,
	payAmt *big.Int,
	reason rpc.PaymentSettleReason,
	logEntry *pem.PayEventMessage) error

func (*Messager) SendPayUnreachableSettleProof ¶

func (m *Messager) SendPayUnreachableSettleProof(
	payID ctype.PayIDType,
	path *rpc.PayPath,
	logEntry *pem.PayEventMessage) error

func (*Messager) SendPaysSettleProof ¶

func (m *Messager) SendPaysSettleProof(
	payIDs []ctype.PayIDType,
	reason rpc.PaymentSettleReason,
	payPaths []*rpc.PayPath,
	logEntry *pem.PayEventMessage) error

func (*Messager) SendPaysSettleRequest ¶

func (m *Messager) SendPaysSettleRequest(
	pays []*entity.ConditionalPay,
	payAmts []*big.Int,
	reason rpc.PaymentSettleReason,
	logEntry *pem.PayEventMessage) ([]*entity.ConditionalPay, error)

func (*MsgQueue) AckMsg ¶

func (m *MsgQueue) AckMsg(cid ctype.CidType, ack, nack uint64) error

Note: this function is not symmetrical to AddMsg() which only adds a message to the queue separately from it being written to storage before. This flows from the different requirements in how messages are created compared to how they are ACKed and deleted.

func (*MsgQueue) AddMsg ¶

func (m *MsgQueue) AddMsg(peer ctype.Addr, cid ctype.CidType, seqnum uint64, msg *rpc.CelerMsg) error

Add a message for a channel. The message itself must have been saved to storage before calling this function. This is typically done atomically inside a store transaction along with other updates, and if successful, AddMsg() is called to notify the message queue.

func (*MsgQueue) AddPeer ¶

func (m *MsgQueue) AddPeer(peer ctype.Addr) error

A peer connected to this server, add its channels to the message queue and start (or resume) managing its messages.

func (*MsgQueue) GetMsg ¶

func (m *MsgQueue) GetMsg(cid ctype.CidType, seqnum uint64) (*rpc.CelerMsg, bool)

GetMsg returns <msg, exist> from the queue

func (*MsgQueue) RemovePeer ¶

func (m *MsgQueue) RemovePeer(peer ctype.Addr) error

A peer disconnected from this server, remove it from the message queue and stop managing its messages.

func (*MsgQueue) ResendMsg ¶

func (m *MsgQueue) ResendMsg(cid ctype.CidType, seqnum uint64) error
