Types

type Agent

type Agent interface {
	Work() chan<- *Work
	SetReturnCh(chan<- *Result)
	Stop()
	Start()
}

Agent can register themself with the worker

type Backend

type Backend interface {
	AccountManager() *accounts.Manager
	BlockChain() *core.BlockChain
	TxPool() *core.TxPool
	ChainDb() ethdb.Database
}

Backend wraps all methods required for mining.

type CpuAgent

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

func NewCpuAgent

func NewCpuAgent(chain consensus.ChainReader, engine consensus.Engine) *CpuAgent

func (*CpuAgent) SetReturnCh

func (self *CpuAgent) SetReturnCh(ch chan<- *Result)

func (*CpuAgent) Start

func (self *CpuAgent) Start()

func (*CpuAgent) Stop

func (self *CpuAgent) Stop()

func (*CpuAgent) Work

func (self *CpuAgent) Work() chan<- *Work

type Miner

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

Miner creates blocks and searches for proof-of-work values.

func New

func New(eth Backend, config *params.ChainConfig, mux *event.TypeMux, engine consensus.Engine) *Miner

func (*Miner) Mining

func (self *Miner) Mining() bool

func (*Miner) Pending

func (self *Miner) Pending(ctx context.Context) (*types.Block, *state.StateDB)

Pending returns the currently pending block and associated state.

func (*Miner) PendingBlock

func (self *Miner) PendingBlock(ctx context.Context) *types.Block

PendingBlock returns the currently pending block.

Note, to access both the pending block and the pending state simultaneously, please use Pending(), as the pending state can change between multiple method calls

func (*Miner) PendingQuery

func (self *Miner) PendingQuery(fn func(*state.StateDB) error) error

PendingQuery calls fn with the pending (ready-only) state.

func (*Miner) Register

func (self *Miner) Register(agent Agent)

func (*Miner) SetEtherbase

func (self *Miner) SetEtherbase(addr common.Address)

func (*Miner) SetExtra

func (self *Miner) SetExtra(extra []byte) error

func (*Miner) Start

func (self *Miner) Start(coinbase common.Address)

func (*Miner) Stop

func (self *Miner) Stop()

func (*Miner) Unregister

func (self *Miner) Unregister(agent Agent)

type RemoteAgent

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

func NewRemoteAgent

func NewRemoteAgent(chain consensus.ChainReader, engine consensus.Engine) *RemoteAgent

func (*RemoteAgent) SetReturnCh

func (a *RemoteAgent) SetReturnCh(returnCh chan<- *Result)

func (*RemoteAgent) Start

func (a *RemoteAgent) Start()

func (*RemoteAgent) Stop

func (a *RemoteAgent) Stop()

func (*RemoteAgent) Work

func (a *RemoteAgent) Work() chan<- *Work

type Result

type Result struct {
	Work  *Work
	Block *types.Block
}

type Work

type Work struct {
	Block *types.Block // the new block
	// contains filtered or unexported fields
}

Work is the workers current environment and holds all of the current state information
