func NewOracleUpdater(logger log.Logger) *alphabetUpdater

NewOracleUpdater returns a new updater.

Types

type AlphabetTraceProvider

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

AlphabetTraceProvider is a [TraceProvider] that provides claims for specific indices in the given trace.

func NewTraceProvider

func NewTraceProvider(state string, depth uint64) *AlphabetTraceProvider

NewTraceProvider returns a new [AlphabetProvider].

func (*AlphabetTraceProvider) AbsolutePreState

func (ap *AlphabetTraceProvider) AbsolutePreState(ctx context.Context) ([]byte, error)

AbsolutePreState returns the absolute pre-state for the alphabet trace.

func (*AlphabetTraceProvider) AbsolutePreStateCommitment

func (ap *AlphabetTraceProvider) AbsolutePreStateCommitment(ctx context.Context) (common.Hash, error)

func (*AlphabetTraceProvider) Get

func (ap *AlphabetTraceProvider) Get(ctx context.Context, i uint64) (common.Hash, error)

Get returns the claim value at the given index in the trace.

func (*AlphabetTraceProvider) GetStepData

func (ap *AlphabetTraceProvider) GetStepData(ctx context.Context, i uint64) ([]byte, []byte, *types.PreimageOracleData, error)
