Types

type Enode 

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

Enode represents a host on the network.

type Enodes 

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

Enodes represents a slice of accounts.

type KeccakState 

type KeccakState interface {
	hash.Hash
	Read([]byte) (int, error)
}

KeccakState wraps sha3.state. In addition to the usual hash methods, it also supports Read to get a variable amount of data from the hash state. Read is faster than Sum because it doesn't copy the internal state, but also modifies the internal state.

func NewKeccakState 

func NewKeccakState() KeccakState

NewKeccakState creates a new KeccakState

type Node 

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

func NewGethNode 

func NewGethNode(datadir string, config *NodeConfig) (stack *Node, _ error)

NewGethNode creates and configures a new Geth node.

func NewGethNodeFataln 

func NewGethNodeFataln(datadir string, config *NodeConfig) (stack *Node)

NewGethNodeFataln creates and configures a new Geth node.

func (*Node) Close 

func (n *Node) Close() error

Close terminates a running node along with all it's services, tearing internal state down. It is not possible to restart a closed node.

func (*Node) GetNodeInfo 

func (n *Node) GetNodeInfo() *NodeInfo

GetNodeInfo gathers and returns a collection of metadata known about the host.

func (*Node) GetPeersInfo

PprofAddress listening address of pprof server.

func (*NodeConfig) SetEthereumDatabaseCache 

func (nc *NodeConfig) SetEthereumDatabaseCache(databaseCache int)

SetEthereumDatabaseCache is the system memory in MB to allocate for database caching. A minimum of 16MB is always reserved.

func (*NodeConfig) SetEthereumEnabled 

func (nc *NodeConfig) SetEthereumEnabled(ethereumEnabled bool)

SetEthereumEnabled specifies whether the node should run the Ethereum protocol.

func (*NodeConfig) SetEthereumGenesis
