ActPool is the interface of actpool

func NewActPool

func NewActPool(g genesis.Genesis, sf protocol.StateReader, cfg Config, opts ...Option) (ActPool, error)

NewActPool constructs a new actpool

type ActQueue

type ActQueue interface {
	Put(action.SealedEnvelope) error
	UpdateQueue() []action.SealedEnvelope
	UpdateAccountState(uint64, *big.Int) []action.SealedEnvelope
	AccountState() (uint64, *big.Int)

}

ActQueue is the interface of actQueue

func NewActQueue

func NewActQueue(ap *actPool, address string, pendingNonce uint64, balance *big.Int, ops ...ActQueueOption) ActQueue

NewActQueue create a new action queue

type ActQueueOption

type ActQueueOption interface {
	SetActQueueOption(*actQueue)
}

ActQueueOption is the option for actQueue.

type Config

type Config struct {
	// MaxNumActsPerPool indicates maximum number of actions the whole actpool can hold
	MaxNumActsPerPool uint64 `yaml:"maxNumActsPerPool"`
	// MaxGasLimitPerPool indicates maximum gas limit the whole actpool can hold
	MaxGasLimitPerPool uint64 `yaml:"maxGasLimitPerPool"`
	// MaxNumActsPerAcct indicates maximum number of actions an account queue can hold
	MaxNumActsPerAcct uint64 `yaml:"maxNumActsPerAcct"`
	// ActionExpiry defines how long an action will be kept in action pool.
	ActionExpiry time.Duration `yaml:"actionExpiry"`

	MinGasPriceStr string `yaml:"minGasPrice"`
	// BlackList lists the account address that are banned from initiating actions
	BlackList []string `yaml:"blackList"`
}

Config is the actpool config

func (Config) MinGasPrice
