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)

DoEstimateGas returns the lowest possible gas limit that allows the transaction to run successfully at block `blockNrOrHash`. It returns error if the transaction would revert, or if there are unexpected failures. The gas limit is capped by both `args.Gas` (if non-nil & non-zero) and `gasCap` (if non-zero).

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
