Functions

func BuildAlphabetPreimage

func BuildAlphabetPreimage(i *big.Int, letter string) []byte

BuildAlphabetPreimage constructs the claim bytes for the index and state item.

func LetterToBytes

func LetterToBytes(letter string) []byte

LetterToBytes converts a letter to a 32 byte array

Types

type AlphabetPrestateProvider

type AlphabetPrestateProvider struct{}

AlphabetPrestateProvider is a stateless [PrestateProvider] that uses a pre-determined, fixed pre-state hash.

func (*AlphabetPrestateProvider) AbsolutePreStateCommitment

func (ap *AlphabetPrestateProvider) AbsolutePreStateCommitment(_ context.Context) (common.Hash, error)

type AlphabetTraceProvider

type AlphabetTraceProvider struct {
	AlphabetPrestateProvider
	// 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) Get

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