Overview

Package types contains the types used to interact with the json-rpc interface. It exists for users of fab3 types to use them without importing the fabric protobuf definitions.

Constants

const (
	// HexEncodedAddressLegnth is 20 bytes, which is 40 chars when hex-encoded
	HexEncodedAddressLegnth = 40
	// HexEncodedTopicLegnth is 32 bytes, which is 64 hex chars when hex-encoded
	HexEncodedTopicLegnth = 64
)

Types

type AddressFilter

type AddressFilter []string // 20 Byte Addresses, OR'd together

func NewAddressFilter

func NewAddressFilter(s string) (AddressFilter, error)

NewAddressFilter takes a string and checks that is the correct length to represent a topic and strips the 0x

type Block

type Block struct {
	BlockData
	// size: QUANTITY - integer the size of this block in bytes.
	// timestamp: QUANTITY - the unix timestamp for when the block was collated.
	Transactions []interface{} `json:"transactions"` // transactions: Array - Array of transaction objects, or 32 Bytes transaction hashes depending on the last given parameter.
}

Block is an eth return struct defined https://github.com/ethereum/wiki/wiki/JSON-RPC#returns-26

func (*Block) MarshalJSON

func (blk *Block) MarshalJSON() ([]byte, error)

MarshalJSON marshals the data differently based on whether transactions are full or just tx hashes

type BlockData

type BlockData struct {
	Number     string `json:"number"`     // number: QUANTITY - the block number. null when its pending block.
	Hash       string `json:"hash"`       // hash: DATA, 32 Bytes - hash of the block. null when its pending block.
	ParentHash string `json:"parentHash"` // parentHash: DATA, 32 Bytes - hash of the parent block.
}

BlockData contains the fields that are constant in a Block object

type EthArgs

type EthArgs struct {
	To       string `json:"to"`
	From     string `json:"from"`
	Gas      string `json:"gas"`
	GasPrice string `json:"gasPrice"`
	Value    string `json:"value"`
	Data     string `json:"data"`
	Nonce    string `json:"nonce"`
}

type GetLogsArgs

type GetLogsArgs struct {
	FromBlock string        `json:"fromBlock,omitempty"`
	ToBlock   string        `json:"toBlock,omitempty"`
	Address   AddressFilter `json:"address,omitempty"`
	Topics    TopicsFilter  `json:"topics,omitempty"`
	BlockHash string        `json:"blockHash,omitempty"`
}

func (*GetLogsArgs) UnmarshalJSON

func (gla *GetLogsArgs) UnmarshalJSON(data []byte) error

type Log

type Log struct {
	Address     string   `json:"address"`
	Topics      []string `json:"topics"`
	Data        string   `json:"data,omitempty"`
	BlockNumber string   `json:"blockNumber"`
	TxHash      string   `json:"transactionHash"`
	TxIndex     string   `json:"transactionIndex"`
	BlockHash   string   `json:"blockHash"`
	Index       string   `json:"logIndex"`
}

type TopicFilter

type TopicFilter []string // 32 Byte Topics, OR'd together

func NewTopicFilter

func NewTopicFilter(s string) (TopicFilter, error)

NewTopicFilter takes a string and checks that is the correct length to represent a topic and strips the 0x

type TopicsFilter

type TopicsFilter []TopicFilter // TopicFilter, AND'd together

func NewTopicsFilter

func NewTopicsFilter(tf ...TopicFilter) TopicsFilter

type Transaction

type Transaction struct {
	BlockHash   string `json:"blockHash"`   // DATA, 32 Bytes - hash of the block where this transaction was in. null when its pending.
	BlockNumber string `json:"blockNumber"` // QUANTITY - block number where this transaction was in. null when its pending.
	To          string `json:"to"`          // DATA, 20 Bytes - address of the receiver. null when its a contract creation transaction.
	// From is generated by EVM Chaincode. Until account generation
	// stabilizes, we are not returning a value.
	//
	// From can be gotten from the Signature on the Transaction Envelope
	//
	From             string `json:"from"`             // DATA, 20 Bytes - address of the sender.
	Input            string `json:"input"`            // DATA - the data send along with the transaction.
	TransactionIndex string `json:"transactionIndex"` // QUANTITY - integer of the transactions index position in the block. null when its pending.
	Hash             string `json:"hash"`             // DATA, 32 Bytes - hash of the transaction.
	GasPrice         string `json:"gasPrice"`         // QUANTITY - gas price provided by the sender in Wei.
	Value            string `json:"value"`            // QUANTITY - value transferred in Wei.
}

Transaction represents an ethereum evm transaction.

func (*Transaction) MarshalJSON

func (tx *Transaction) MarshalJSON() ([]byte, error)

MarshalJSON will json marshal the tx object as well as setting the Gas Price and Value fields as Ox0

type TxReceipt

type TxReceipt struct {
	TransactionHash   string `json:"transactionHash"`
	TransactionIndex  string `json:"transactionIndex"`
	BlockHash         string `json:"blockHash"`
	BlockNumber       string `json:"blockNumber"`
	ContractAddress   string `json:"contractAddress,omitempty"`
	GasUsed           int    `json:"gasUsed"`
	CumulativeGasUsed int    `json:"cumulativeGasUsed"`
	To                string `json:"to"`
	Logs              []Log  `json:"logs"`
	Status            string `json:"status"`
	From              string `json:"from"`
