Variables

var ErrNotFound = errors.New("not found")

NotFound is returned by API methods if the requested item does not exist.

type CallMsg Uses

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.

type ChainReader Uses

type ChainReader interface {
}

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.

type ChainStateReader Uses

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.

type ChainSyncReader Uses

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.

type ContractCaller Uses

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.

type FilterQuery Uses

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.

type GasEstimator Uses

type GasEstimator interface {
    EstimateGas(ctx context.Context, call CallMsg) (uint64, error)
}

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.

type GasPricer Uses

type GasPricer interface {
    SuggestGasPrice(ctx context.Context) (*big.Int, error)
}

GasPricer wraps the gas price oracle, which monitors the blockchain to determine the optimal gas price given current fee market conditions.

type PendingContractCaller Uses

type PendingContractCaller interface {
    PendingCallContract(ctx context.Context, call CallMsg) ([]byte, error)
}

PendingContractCaller can be used to perform calls against the pending state.

type PendingStateEventer Uses

type PendingStateEventer interface {
    SubscribePendingTransactions(ctx context.Context, ch chan<- *modules.Transaction) (Subscription, error)
}

A PendingStateEventer provides access to real time notifications about changes to the pending state.

type PendingStateReader Uses

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.

type Subscription Uses

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.

type SyncProgress Uses

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 synchronizing with the palletone network.

type TransactionReader Uses

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(ctx context.Context, txHash common.Hash) (tx *modules.Transaction, isPending bool, err error)
}

TransactionReader provides access to past transactions and their receipts. Implementations may impose arbitrary restrictions on the transactions and receipts that can be retrieved. Historic transactions may not be available.

Avoid relying on this interface if possible. Contract logs (through the LogFilterer interface) are more reliable and usually safer in the presence of chain reorganizations.

The returned error is NotFound if the requested item does not exist.

type TransactionSender Uses

type TransactionSender interface {
    SendTransaction(ctx context.Context, tx *modules.Transaction) 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 reorganization. type LogFilterer interface {

FilterLogs(ctx context.Context, q FilterQuery) ([]types.Log, error)
SubscribeFilterLogs(ctx context.Context, q FilterQuery, ch chan<- types.Log) (Subscription, 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.
