Types ¶

type BroadcastedTransaction ¶

type BroadcastedTransaction struct {
	Transaction   core.Transaction
	DeclaredClass core.Class
	PaidFeeOnL1   *felt.Felt
}

type Pool ¶

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

Pool represents a blockchain mempool, managing transactions using both an in-memory and persistent database.

func New ¶

func New(mainDB db.KeyValueStore, bc blockchain.Reader, maxNumTxns int, log utils.SimpleLogger) *Pool

New initialises the Pool and starts the database writer goroutine. It is the responsibility of the caller to execute the closer function.

func (*Pool) Close ¶ added in v0.14.4

func (p *Pool) Close()

func (*Pool) Len ¶

func (p *Pool) Len() int

Len returns the number of transactions in the in-memory pool

func (*Pool) LenDB ¶

func (p *Pool) LenDB() (int, error)

func (*Pool) LoadFromDB ¶

func (p *Pool) LoadFromDB() error

LoadFromDB restores the in-memory transaction pool from the database

func (*Pool) Pop ¶

func (p *Pool) Pop() (BroadcastedTransaction, error)

Pop returns the transaction with the highest priority from the in-memory pool

func (*Pool) PopBatch ¶ added in v0.14.4

func (p *Pool) PopBatch(numToPop int) ([]BroadcastedTransaction, error)

PopBatch returns a batch of transactions with the highest priority from the in-memory pool

func (*Pool) Push ¶

func (p *Pool) Push(userTxn *BroadcastedTransaction) error

Push queues a transaction to the pool

func (*Pool) Remove ¶

func (p *Pool) Remove(hash ...*felt.Felt) error

Remove removes a set of transactions from the pool todo: should be called by the builder to remove txns from the db everytime a new block is stored. todo: in the consensus+p2p world, the txns should also be removed from the in-memory pool.

func (*Pool) Wait ¶

func (p *Pool) Wait() <-chan struct{}
