Functions

func AccessList 

func AccessList(ctx context.Context, b Backend, blockNrOrHash rpc.BlockNumberOrHash, args TransactionArgs) (acl types.AccessList, gasUsed uint64, vmErr error, err error)

AccessList creates an access list for the given transaction. If the accesslist creation fails an error is returned. If the transaction itself fails, an vmErr is returned.

func DoCall 

func DoCall(ctx context.Context, b Backend, args TransactionArgs, blockNrOrHash rpc.BlockNumberOrHash, overrides *StateOverride, blockOverrides *BlockOverrides, timeout time.Duration, globalGasCap uint64) (*core.ExecutionResult, error)

func DoEstimateGas 

func DoEstimateGas(ctx context.Context, b Backend, args TransactionArgs, blockNrOrHash rpc.BlockNumberOrHash, overrides *StateOverride, gasCap uint64) (hexutil.Uint64, error)

func GetAPIs 

func GetAPIs(apiBackend Backend) []rpc.API

func RPCMarshalBlock 

func RPCMarshalBlock(block *types.Block, inclTx bool, fullTx bool, config *params.ChainConfig) map[string]interface{}

RPCMarshalBlock converts the given block to the RPC output which depends on fullTx. If inclTx is true transactions are returned. When fullTx is true the returned block contains full transaction details, otherwise it will only contain transaction hashes.

func RPCMarshalHeader 

func RPCMarshalHeader(head *types.Header) map[string]interface{}

RPCMarshalHeader converts the given header to the RPC output .

func SubmitTransaction 

func SubmitTransaction(ctx context.Context, b Backend, tx *types.Transaction) (common.Hash, error)

SubmitTransaction is a helper function that submits tx to txPool and logs a message.

Types

type AccountResult 

type AccountResult struct {
	Address      common.Address  `json:"address"`
	AccountProof []string        `json:"accountProof"`
	Balance      *hexutil.Big    `json:"balance"`

Result structs for GetProof

type AddrLocker 

type AddrLocker struct {

}

func (*AddrLocker) LockAddr 

func (l *AddrLocker) LockAddr(address common.Address)

func (*AddrLocker) UnlockAddr 

func (l *AddrLocker) UnlockAddr(address common.Address)

UnlockAddr unlocks the mutex of the given account.

Backend interface provides the common API services (that are provided by both full and light clients) with access to necessary functions.

type BadBlockArgs added in v0.4.1 

type BadBlockArgs struct {
	Hash   common.Hash            `json:"hash"`

	RLP    string                 `json:"rlp"`
	Reason *core.BadBlockReason   `json:"reason"`
}

Note: this API is moved directly from ./eth/api.go to ensure that it is available under an API that is enabled by default without duplicating the code and serving the same API in the original location as well without creating a cyclic import.

BadBlockArgs represents the entries in the list returned when bad blocks are queried.

	// contains filtered or unexported fields
}

BlockChainAPI provides an API to access Ethereum blockchain data.
