Types

type OutputPrestateProvider

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

func NewPrestateProvider

func NewPrestateProvider(rollupClient OutputRollupClient, prestateBlock uint64) *OutputPrestateProvider

func (*OutputPrestateProvider) AbsolutePreStateCommitment

func (o *OutputPrestateProvider) AbsolutePreStateCommitment(ctx context.Context) (hash common.Hash, err error)

type OutputRollupClient

type OutputRollupClient interface {
	OutputAtBlock(ctx context.Context, blockNum uint64) (*eth.OutputResponse, error)
	SafeHeadAtL1Block(ctx context.Context, l1BlockNum uint64) (*eth.SafeHeadResponse, error)
}

type OutputTraceProvider

type OutputTraceProvider struct {
	types.PrestateProvider
	// contains filtered or unexported fields
}

OutputTraceProvider is a types.TraceProvider implementation that uses output roots for given L2 Blocks as a trace.

func NewTraceProvider

func NewTraceProvider(logger log.Logger, prestateProvider types.PrestateProvider, rollupProvider OutputRollupClient, l2Client utils.L2HeaderSource, l1Head eth.BlockID, gameDepth types.Depth, prestateBlock, poststateBlock uint64) *OutputTraceProvider

func (*OutputTraceProvider) ClaimedBlockNumber

func (o *OutputTraceProvider) ClaimedBlockNumber(pos types.Position) (uint64, error)

ClaimedBlockNumber returns the block number for a position restricted only by the claimed L2 block number. The returned block number may be after the safe head reached by processing batch data up to the game's L1 head

func (*OutputTraceProvider) Get

func (o *OutputTraceProvider) Get(ctx context.Context, pos types.Position) (common.Hash, error)

func (*OutputTraceProvider) GetL2BlockNumberChallenge

func (o *OutputTraceProvider) GetL2BlockNumberChallenge(ctx context.Context) (*types.InvalidL2BlockNumberChallenge, error)

func (*OutputTraceProvider) GetStepData

func (o *OutputTraceProvider) GetStepData(_ context.Context, _ types.Position) (prestate []byte, proofData []byte, preimageData *types.PreimageOracleData, err error)

GetStepData is not supported in the OutputTraceProvider.

func (*OutputTraceProvider) HonestBlockNumber

func (o *OutputTraceProvider) HonestBlockNumber(ctx context.Context, pos types.Position) (uint64, error)

HonestBlockNumber returns the block number for a position in the game restricted to the minimum of the claimed L2 block number or the safe head reached by processing batch data up to the game's L1 head. This is used when posting honest output roots to ensure that only roots supported by L1 data are posted

type ProposalTraceProviderCreator

type ProposalTraceProviderCreator func(ctx context.Context, localContext common.Hash, depth types.Depth, agreed contracts.Proposal, claimed contracts.Proposal) (types.TraceProvider, error)

type ProviderCache

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

func NewProviderCache

func NewProviderCache(m caching.Metrics, metricsLabel string, creator ProposalTraceProviderCreator) *ProviderCache

func (*ProviderCache) GetOrCreate

func (c *ProviderCache) GetOrCreate(ctx context.Context, localContext common.Hash, depth types.Depth, agreed contracts.Proposal, claimed contracts.Proposal) (types.TraceProvider, error)
