Types

type MemPool 

type MemPool[VoteRank spenddag.VoteRankType[VoteRank]] struct {
	// contains filtered or unexported fields
}

MemPool is a component that manages the state of transactions that are not yet included in the ledger state.

func New

	vm mempool.VM,
	stateResolver mempool.StateResolver,
	mutationsFunc func(iotago.SlotIndex) (kvstore.KVStore, error),
	spendDAG spenddag.SpendDAG[iotago.TransactionID, mempool.StateID, VoteRank],
	apiProvider iotago.APIProvider,
	errorHandler func(error),
	opts ...options.Option[MemPool[VoteRank]],
) *MemPool[VoteRank]

New is the constructor of the MemPool.
