Types ¶

type ConsistencyLevel ¶

type ConsistencyLevel uint8

func (ConsistencyLevel) Commitment ¶

func (c ConsistencyLevel) Commitment() (rpc.CommitmentType, error)

type EventSubscriptionData ¶

type EventSubscriptionData struct {
	Jsonrpc string `json:"jsonrpc"`
	Method  string `json:"method"`
	Params  *struct {
		Result struct {
			Context struct {
				Slot int64 `json:"slot"`
			} `json:"context"`
			Value struct {
				Pubkey  string `json:"pubkey"`
				Account struct {
					Lamports   int64    `json:"lamports"`
					Data       []string `json:"data"`
					Owner      string   `json:"owner"`
					Executable bool     `json:"executable"`
					RentEpoch  int64    `json:"rentEpoch"`
				} `json:"account"`
			} `json:"value"`
		} `json:"result"`
		Subscription int `json:"subscription"`
	} `json:"params"`
}

type EventSubscriptionError ¶

type EventSubscriptionError struct {
	Jsonrpc string `json:"jsonrpc"`
	Error   struct {
		Code    int     `json:"code"`
		Message *string `json:"message"`
	} `json:"error"`
	ID string `json:"id"`
}

type M ¶

type M map[string]interface{}

type MessagePublicationAccount ¶

type MessagePublicationAccount struct {
	VaaVersion       uint8
	ConsistencyLevel uint8
	EmitterAuthority vaa.Address
	MessageStatus    uint8
	Gap              [3]byte
	SubmissionTime   uint32
	Nonce            uint32
	Sequence         uint64
	EmitterChain     uint16

type PostMessageData ¶

type PostMessageData struct {

	ChainID       vaa.ChainID        // ChainID
	ReceiveObsReq bool               // if false, this watcher will not get access to the observation request channel
	Rpc           string             // RPC URL
	Websocket     string             // Websocket URL
	Contract      string             // hex representation of the contract address
	Commitment    solana_rpc.CommitmentType
}
