Functions

func NewDatabase 

func NewDatabase(db ethdb.Database) ethstate.Database

func NewDatabaseWithConfig 

func NewDatabaseWithConfig(db ethdb.Database, config *triedb.Config) ethstate.Database

func NewDatabaseWithNodeDB added in v0.5.3 

func NewDatabaseWithNodeDB(db ethdb.Database, triedb *triedb.Database) ethstate.Database

func WithConcurrentWorkers added in v0.7.1 

func WithConcurrentWorkers(prefetchers int) ethstate.PrefetcherOption

Types

type Database 

type Database = ethstate.Database

type Dump 

type Dump = ethstate.Dump

type DumpAccount 

type DumpAccount = ethstate.DumpAccount

type DumpCollector 

type DumpCollector = ethstate.DumpCollector

type DumpConfig 

type DumpConfig = ethstate.DumpConfig

type StateDB 

type StateDB struct {
	*ethstate.StateDB
	// contains filtered or unexported fields
}

StateDB structs within the ethereum protocol are used to store anything within the merkle trie. StateDBs take care of caching and storing nested states. It's the general query interface to retrieve:

* Contracts * Accounts

Once the state is committed, tries cached in stateDB (including account trie, storage tries) will no longer be functional. A new state instance must be created with new root and updated database for accessing post- commit states.

func New 

func New(root common.Hash, db Database, snaps ethstate.SnapshotTree) (*StateDB, error)

New creates a new state from a given trie.

func (*StateDB) Copy 

func (s *StateDB) Copy() *StateDB

func (*StateDB) GetState 

func (s *StateDB) GetState(addr common.Address, hash common.Hash) common.Hash

GetState retrieves a value from the given account's storage trie.

func (*StateDB) GetTxHash added in v0.5.6 

func (s *StateDB) GetTxHash() common.Hash

GetTxHash returns the current tx hash on the StateDB set by SetTxContext.

func (*StateDB) SetState 

func (s *StateDB) SetState(addr common.Address, key, value common.Hash)

func (*StateDB) SetTxContext added in v0.5.3 

func (s *StateDB) SetTxContext(thash common.Hash, ti int)

SetTxContext sets the current transaction hash and index which are used when the EVM emits new state logs. It should be invoked before transaction execution.

type Trie 

type Trie = ethstate.Trie
