func NewPublicDebugAPI(eth *Ethereum) *PublicDebugAPI

NewPublicDebugAPI creates a new API definition for the full node- related public debug methods of the Ethereum service.

func (*PublicDebugAPI) AccountRange 

func (api *PublicDebugAPI) AccountRange(blockNrOrHash rpc.BlockNumberOrHash, start []byte, maxResults int, nocode, nostorage, incompletes bool) (state.IteratorDump, error)

AccountRangeAt enumerates all accounts in the given block and start point in paging request

func (*PublicDebugAPI) DumpBlock 

func (api *PublicDebugAPI) DumpBlock(blockNr rpc.BlockNumber) (state.Dump, error)

DumpBlock retrieves the entire state of the database at a given block.

type PublicEthereumAPI 

type PublicEthereumAPI struct {
	// contains filtered or unexported fields
}

PublicEthereumAPI provides an API to access Ethereum full node-related information.

func NewPublicEthereumAPI 

func NewPublicEthereumAPI(e *Ethereum) *PublicEthereumAPI

NewPublicEthereumAPI creates a new Ethereum protocol API for full nodes.

func (*PublicEthereumAPI) ChainId 

func (api *PublicEthereumAPI) ChainId() hexutil.Uint64

ChainId is the EIP-155 replay-protection chain id for the current ethereum chain config.

func (*PublicEthereumAPI) Coinbase 

func (api *PublicEthereumAPI) Coinbase() (common.Address, error)

Coinbase is the address that mining rewards will be send to

func (*PublicEthereumAPI) Hashrate 

func (api *PublicEthereumAPI) Hashrate() hexutil.Uint64

Hashrate returns the POW hashrate

type PublicMinerAPI 

type PublicMinerAPI struct {
	// contains filtered or unexported fields
}

PublicMinerAPI provides an API to control the miner. It offers only methods that operate on data that pose no security risk when it is publicly accessible.

func NewPublicMinerAPI 

func NewPublicMinerAPI(e *Ethereum) *PublicMinerAPI

NewPublicMinerAPI create a new PublicMinerAPI instance.

func (*PublicMinerAPI) Mining 

func (api *PublicMinerAPI) Mining() bool

Mining returns an indication if this node is currently mining.

type StdTraceConfig 

type StdTraceConfig struct {
	*vm.LogConfig
	Reexec *uint64
	TxHash common.Hash
}

StdTraceConfig holds extra parameters to standard-json trace functions.

type StorageRangeResult 

type StorageRangeResult struct {
	Storage storageMap   `json:"storage"`
	NextKey *common.Hash `json:"nextKey"` // nil if Storage includes the last key in the trie.
}

StorageRangeResult is the result of a debug_storageRangeAt API call.

type TraceConfig 

type TraceConfig struct {
	*vm.LogConfig
	Tracer  *string
	Timeout *string
	Reexec  *uint64
}

TraceConfig holds extra parameters to trace functions.
