Types

type Module

type Module struct {
	Store *storage.MemCachedStore
	// contains filtered or unexported fields
}

Module represents module for local processing of state roots.

func NewModule

func NewModule(bc blockchainer.Blockchainer, log *zap.Logger, s *storage.MemCachedStore) *Module

NewModule returns new instance of stateroot module.

func (*Module) AddMPTBatch

func (s *Module) AddMPTBatch(index uint32, b mpt.Batch, cache *storage.MemCachedStore) (*mpt.Trie, *state.MPTRoot, error)

AddMPTBatch updates using provided batch.

func (*Module) AddStateRoot

func (s *Module) AddStateRoot(sr *state.MPTRoot) error

AddStateRoot adds validated state root provided by network.

func (*Module) CurrentLocalStateRoot

func (s *Module) CurrentLocalStateRoot() util.Uint256

CurrentLocalStateRoot returns hash of the local state root.

func (*Module) CurrentValidatedHeight

func (s *Module) CurrentValidatedHeight() uint32

CurrentValidatedHeight returns current state root validated height.

func (*Module) GetStateProof

func (s *Module) GetStateProof(root util.Uint256, key []byte) ([][]byte, error)

func (*Module) Init

func (s *Module) Init(height uint32, enableRefCount bool) error

Init initializes state root module at the given height.

func (*Module) SetUpdateValidatorsCallback

func (s *Module) SetUpdateValidatorsCallback(f func(uint32, keys.PublicKeys))

SetUpdateValidatorsCallback sets callback for sending signed root.

func (*Module) UpdateCurrentLocal

func (s *Module) UpdateCurrentLocal(mpt *mpt.Trie, sr *state.MPTRoot)

UpdateCurrentLocal updates local caches using provided state root.
