Types

type Config

type Config struct {
	MaxPoolSize uint64

	WeightLimits map[transaction.Weight]uint64
}

Config is a transaction pool configuration.

type TxPool

type TxPool interface {
	// Name is the transaction pool implementation name.
	Name() string

	// Add adds a single transaction into the transaction pool.
	Add(tx *transaction.CheckedTransaction) error

	// GetBatch gets a transaction batch from the transaction pool.
	GetBatch(force bool) []*transaction.CheckedTransaction

	// RemoveBatch removes a batch from the transaction pool.
	RemoveBatch(batch []hash.Hash) error

	// IsQueued returns whether a transaction is in the queue already.
	IsQueued(txHash hash.Hash) bool

	// Size returns the number of transactions in the transaction pool.
	Size() uint64

	// UpdateConfig updates the transaction pool config.
	UpdateConfig(Config) error

	// Clear clears the transaction pool.
