}

TrieStats is used to collect the trie statistics for the given rootHash

type TrieStorageInteractor 

type TrieStorageInteractor interface {
	BaseStorer
	GetIdentifier() string
	GetStateStatsHandler() StateStatisticsHandler
}

TrieStorageInteractor defines the methods used for interacting with the trie storage

type TrieType 

type TrieType string

TrieType defines the type of the trie 

const (
	// MainTrie represents the main trie in which all the accounts and SC code are stored
	MainTrie TrieType = "mainTrie"

	// DataTrie represents a data trie in which all the data related to an account is stored
	DataTrie TrieType = "dataTrie"
)

type TriesHolder 

type TriesHolder interface {
	Put([]byte, Trie)
	Replace(key []byte, tr Trie)
	Get([]byte) Trie
	GetAll() []Trie
	Reset()
	IsInterfaceNil() bool
}

TriesHolder is used to store multiple tries

type TriesStatisticsCollector 

type TriesStatisticsCollector interface {
	Add(trieStats TrieStatisticsHandler, trieType TrieType)
	Print()
	GetNumNodes() uint64
}

TriesStatisticsCollector is used to merge the statistics for multiple tries
