var NotFound = errors.New("not found")
NotFound is returned by API methods if the requested item does not exist.
Functions ¶
This section is empty.
Types ¶
type CallMsg ¶
type CallMsg struct {
From common.Address // the sender of the 'transaction'
To *common.Address // the destination contract (nil for contract creation)
Gas uint64 // if 0, the call executes with near-infinite gas
GasPrice *big.Int // wei <-> gas exchange ratio
Value *big.Int // amount of wei sent along with the call
Data []byte // input data, usually an ABI-encoded contract method invocation
}
CallMsg contains parameters for contract calls. CallMsg 구조체는 계약 호출을 위한 파라미터를 포함한다
type ChainReader ¶
type ChainReader interface {
BlockByHash(ctx context.Context, hash common.Hash) (*types.Block, error)
BlockByNumber(ctx context.Context, number *big.Int) (*types.Block, error)
HeaderByHash(ctx context.Context, hash common.Hash) (*types.Header, error)
HeaderByNumber(ctx context.Context, number *big.Int) (*types.Header, error)
TransactionCount(ctx context.Context, blockHash common.Hash) (uint, error)
TransactionInBlock(ctx context.Context, blockHash common.Hash, index uint) (*types.Transaction, error)
// This method subscribes to notifications about changes of the head block of
// the canonical chain.
// 이 함수는 캐노니컬 체인의 헤드블록의 변경에 대한 노티를 구독한다
SubscribeNewHead(ctx context.Context, ch chan<- *types.Header) (Subscription, error)
}
ChainReader provides access to the blockchain. The methods in this interface access raw data from either the canonical chain (when requesting by block number) or any blockchain fork that was previously downloaded and processed by the node. The block number argument can be nil to select the latest canonical block. Reading block headers should be preferred over full blocks whenever possible.
The returned error is NotFound if the requested item does not exist. 체인리더 인터페이스는 블록체인에 대한 접근을 제공한다. 이 인터페이스 내부의 함수들은 캐노니컬 체인(블록넘버로 접근했을때)과 기존에 이 노드에 다운받았거나 처리되었던 다른 포크체인의 저수준 데이터를 접근한다. 블록 번호 인자는 마지막 캐노니컬 블록을 선택하기 위해 nil일수 있다. 블록헤더를 읽는것은 풀불록이 가능한 상태에서 읽는것이 선호된다.
type ChainStateReader ¶
type ChainStateReader interface {
BalanceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (*big.Int, error)
StorageAt(ctx context.Context, account common.Address, key common.Hash, blockNumber *big.Int) ([]byte, error)
CodeAt(ctx context.Context, account common.Address, blockNumber *big.Int) ([]byte, error)
NonceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (uint64, error)
}
ChainStateReader wraps access to the state trie of the canonical blockchain. Note that implementations of the interface may be unable to return state values for old blocks. In many cases, using CallContract can be preferable to reading raw contract storage. 체인상태리더 인터페이스는 캐노니컬 블록체인의 상태트라이에 대한 접근을 포함한다. 인터페이스의 구현들은 오래된 블럭에 대한 상태 값을 반환하는 것이 불가능할수도 있다는 것을 기억하라 대부분의 상황에서, 저수준 계약 저장소를 읽는 것은 CallContract 함수를 사용하는 것이 선호된다
type ChainSyncReader ¶
type ChainSyncReader interface {
SyncProgress(ctx context.Context) (*SyncProgress, error)
}
ChainSyncReader wraps access to the node's current sync status. If there's no sync currently running, it returns nil. 체인싱크리더 인터페이스는 노드의 현재 동기화 상태에 접근을 포함한다. 만약 현재 싱크중이지 않다면 nil을 리턴한다
type ContractCaller ¶
type ContractCaller interface {
CallContract(ctx context.Context, call CallMsg, blockNumber *big.Int) ([]byte, error)
}
A ContractCaller provides contract calls, essentially transactions that are executed by the EVM but not mined into the blockchain. ContractCall is a low-level method to execute such calls. For applications which are structured around specific contracts, the abigen tool provides a nicer, properly typed way to perform calls. 계약호출 인터페이스는블록체인에 채굴되어 포함되지 않았지만 EVM에 의해 실행될 필수 트렌젝션들에 대한 계약 호출을 제공한다 이 인터페이스는 위와같은 호출을 실행시키는 저수준 함수이다. 특정계약을 구성하는 프로그램들을 위해 abigen tool 인터페이스는 호출을 수행하기 위한 보다 좋고 적합한 방법을 제공한다
type FilterQuery ¶
type FilterQuery struct {
FromBlock *big.Int // beginning of the queried range, nil means genesis block
ToBlock *big.Int // end of the range, nil means latest block
Addresses []common.Address // restricts matches to events created by specific contracts
// The Topic list restricts matches to particular event topics. Each event has a list
// of topics. Topics matches a prefix of that list. An empty element slice matches any
// topic. Non-empty elements represent an alternative that matches any of the
// contained topics.
//
// Examples:
// {} or nil matches any topic list
// {{A}} matches topic A in first position
// {{}, {B}} matches any topic in first position, B in second position
// {{A}}, {B}} matches topic A in first position, B in second position
// {{A, B}}, {C, D}} matches topic (A OR B) in first position, (C OR D) in second position
Topics [][]common.Hash
}
FilterQuery contains options for contract log filtering. 필터쿼리 구조체는 계약 로그 필터링을 위한 옵션을 포함한다
type GasEstimator ¶
GasEstimator wraps EstimateGas, which tries to estimate the gas needed to execute a specific transaction based on the pending state. There is no guarantee that this is the true gas limit requirement as other transactions may be added or removed by miners, but it should provide a basis for setting a reasonable default. GasEstimator 인터페이스는 대기상태에 따른 특정 트렌젝션을 실행하기 위한 가스를 예측하기 위한 EstimateGas 함수를 포함한다.
type GasPricer ¶
GasPricer wraps the gas price oracle, which monitors the blockchain to determine the optimal gas price given current fee market conditions. GasPricer 인터페이스는 블록체인이 주어진 현재 마켓의 수수료 상태에서 최적의 가스가격을 결정하도록 모니터링 하는 GasPriceOracle을 포함한다
type LogFilterer ¶
type LogFilterer interface {
FilterLogs(ctx context.Context, q FilterQuery) ([]types.Log, error)
SubscribeFilterLogs(ctx context.Context, q FilterQuery, ch chan<- types.Log) (Subscription, error)
}
LogFilterer provides access to contract log events using a one-off query or continuous event subscription.
Logs received through a streaming query subscription may have Removed set to true, indicating that the log was reverted due to a chain reorganisation. 로그 필터러 인터페이스는 한번의 쿼리나 연속적인 이벤트 구독을 이용하는 계약 로그 이벤트에 대한 접근을 제공한다
type PendingContractCaller ¶
type PendingContractCaller interface {
PendingCallContract(ctx context.Context, call CallMsg) ([]byte, error)
}
PendingContractCaller can be used to perform calls against the pending state. PendingContractCaller 인터페이스는 대기상태에 대한 수행 호출을 위해 사용될수 있다
type PendingStateEventer ¶
type PendingStateEventer interface {
SubscribePendingTransactions(ctx context.Context, ch chan<- *types.Transaction) (Subscription, error)
}
A PendingStateEventer provides access to real time notifications about changes to the pending state. PendingStateEventer 인터페이스는 대기상태의 변화에 대한 실시간 알람을 제공한다
type PendingStateReader ¶
type PendingStateReader interface {
PendingBalanceAt(ctx context.Context, account common.Address) (*big.Int, error)
PendingStorageAt(ctx context.Context, account common.Address, key common.Hash) ([]byte, error)
PendingCodeAt(ctx context.Context, account common.Address) ([]byte, error)
PendingNonceAt(ctx context.Context, account common.Address) (uint64, error)
PendingTransactionCount(ctx context.Context) (uint, error)
}
A PendingStateReader provides access to the pending state, which is the result of all known executable transactions which have not yet been included in the blockchain. It is commonly used to display the result of ’unconfirmed’ actions (e.g. wallet value transfers) initiated by the user. The PendingNonceAt operation is a good way to retrieve the next available transaction nonce for a specific account. PendingStateReader 인터페이스는 아직 블록체인에 포함되지 않은 모든 알려진 실행가능한 트렌젝션의 대기상태로의 접근을 지원한다
type Subscription ¶
type Subscription interface {
// Unsubscribe cancels the sending of events to the data channel
// and closes the error channel.
Unsubscribe()
// Err returns the subscription error channel. The error channel receives
// a value if there is an issue with the subscription (e.g. the network connection
// delivering the events has been closed). Only one value will ever be sent.
// The error channel is closed by Unsubscribe.
Err() <-chan error
}
Subscription represents an event subscription where events are delivered on a data channel. Subscription 인터페이스는 데이터 채널위에서 전송되는 이벤트를 구독한다.
type SyncProgress ¶
type SyncProgress struct {
StartingBlock uint64 // Block number where sync began
CurrentBlock uint64 // Current block number where sync is at
HighestBlock uint64 // Highest alleged block number in the chain
PulledStates uint64 // Number of state trie entries already downloaded
KnownStates uint64 // Total number of state trie entries known about
}
SyncProgress gives progress indications when the node is synchronising with the Ethereum network. SyncProgress 구조체는 노드가 이더리움 네트워크가 싱크중일때 진행상황을 알려준다
type TransactionReader ¶
type TransactionReader interface {
// TransactionByHash checks the pool of pending transactions in addition to the
// blockchain. The isPending return value indicates whether the transaction has been
// mined yet. Note that the transaction may not be part of the canonical chain even if
// it's not pending.
// TransactionByHash 함수는 블록체인에 추가할 대기 트렌젝션 풀을 체크한다.
// isPending의 반환값은 아직 마이닝되지 않은 트렌젝션을 가리킨다.
// 그 트렌젝션은 대기중이 아니라도 캐노니컬 체인의 부분이 아닐수 있다는 것을 기억하라.
TransactionByHash(ctx context.Context, txHash common.Hash) (tx *types.Transaction, isPending bool, err error)
// TransactionReceipt returns the receipt of a mined transaction. Note that the
// transaction may not be included in the current canonical chain even if a receipt
// exists.
// Transaction Receipt 함수는 채굴된 트렌젝션의 영수증을 반환한다.
// 영수증이 존재하더라도 그 트렌젝션은 현재 캐노니컬 체인에 포함되지 않을수 있다.
TransactionReceipt(ctx context.Context, txHash common.Hash) (*types.Receipt, error)
}
type TransactionSender ¶
type TransactionSender interface {
SendTransaction(ctx context.Context, tx *types.Transaction) error
}
TransactionSender wraps transaction sending. The SendTransaction method injects a signed transaction into the pending transaction pool for execution. If the transaction was a contract creation, the TransactionReceipt method can be used to retrieve the contract address after the transaction has been mined.
The transaction must be signed and have a valid nonce to be included. Consumers of the API can use package accounts to maintain local private keys and need can retrieve the next available nonce using PendingNonceAt. TransactionSender 인터페이스는 trasanction 전송을 포함한다. SendTransaction 함수는 사인된 트렌젝션을 실행하기 위해 대기 트렌젝션 풀에 주입한다. 만약 트렌젝션이 계약의 생성이였다면, 트렌젝션이 마이닝 된후 계약 주소를 반환받기 위해 TransactionReceipt 함수가 사용될 수 있다.
