Types ¶

type AdminBackend ¶

type AdminBackend interface {
	Start(ctx context.Context) error
	Stop(ctx context.Context) error
	AddL2RPC(ctx context.Context, rpc string) error
}

type AdminFrontend ¶

type AdminFrontend struct {
	Supervisor Backend
}

func (*AdminFrontend) AddL2RPC ¶ added in v1.9.3

func (a *AdminFrontend) AddL2RPC(ctx context.Context, rpc string) error

AddL2RPC adds a new L2 chain to the supervisor backend

func (*AdminFrontend) Start ¶

func (a *AdminFrontend) Start(ctx context.Context) error

Start starts the service, if it was previously stopped.

func (*AdminFrontend) Stop ¶

func (a *AdminFrontend) Stop(ctx context.Context) error

Stop stops the service, if it was previously started.

type Backend ¶

type Backend interface {
	AdminBackend
	QueryBackend
	UpdatesBackend
}

type QueryBackend ¶

type QueryBackend interface {
	CheckMessage(identifier types.Identifier, payloadHash common.Hash) (types.SafetyLevel, error)
	CheckMessages(messages []types.Message, minSafety types.SafetyLevel) error
	CrossDerivedFrom(ctx context.Context, chainID types.ChainID, derived eth.BlockID) (derivedFrom eth.BlockRef, err error)
	UnsafeView(ctx context.Context, chainID types.ChainID, unsafe types.ReferenceView) (types.ReferenceView, error)
	SafeView(ctx context.Context, chainID types.ChainID, safe types.ReferenceView) (types.ReferenceView, error)
	Finalized(ctx context.Context, chainID types.ChainID) (eth.BlockID, error)
}

type QueryFrontend ¶

type QueryFrontend struct {
	Supervisor QueryBackend
}

func (*QueryFrontend) CheckMessage ¶

func (q *QueryFrontend) CheckMessage(identifier types.Identifier, payloadHash common.Hash) (types.SafetyLevel, error)

CheckMessage checks the safety-level of an individual message. The payloadHash references the hash of the message-payload of the message.

func (*QueryFrontend) CheckMessages ¶ added in v1.9.1

func (q *QueryFrontend) CheckMessages(
	messages []types.Message,
	minSafety types.SafetyLevel) error

CheckMessage checks the safety-level of a collection of messages, and returns if the minimum safety-level is met for all messages.

func (*QueryFrontend) CrossDerivedFrom ¶ added in v1.9.5

func (q *QueryFrontend) CrossDerivedFrom(ctx context.Context, chainID types.ChainID, derived eth.BlockID) (derivedFrom eth.BlockRef, err error)

func (*QueryFrontend) Finalized ¶ added in v1.9.5

func (q *QueryFrontend) Finalized(ctx context.Context, chainID types.ChainID) (eth.BlockID, error)

func (*QueryFrontend) SafeView ¶ added in v1.9.5

func (q *QueryFrontend) SafeView(ctx context.Context, chainID types.ChainID, safe types.ReferenceView) (types.ReferenceView, error)

func (*QueryFrontend) UnsafeView ¶ added in v1.9.5

func (q *QueryFrontend) UnsafeView(ctx context.Context, chainID types.ChainID, unsafe types.ReferenceView) (types.ReferenceView, error)

type UpdatesBackend ¶ added in v1.9.5

type UpdatesBackend interface {
	UpdateLocalUnsafe(ctx context.Context, chainID types.ChainID, head eth.BlockRef) error
	UpdateLocalSafe(ctx context.Context, chainID types.ChainID, derivedFrom eth.BlockRef, lastDerived eth.BlockRef) error
	UpdateFinalizedL1(ctx context.Context, chainID types.ChainID, finalized eth.BlockRef) error
}

type UpdatesFrontend ¶ added in v1.9.5

type UpdatesFrontend struct {
	Supervisor UpdatesBackend
}

func (*UpdatesFrontend) UpdateFinalizedL1 ¶ added in v1.9.5

func (u *UpdatesFrontend) UpdateFinalizedL1(ctx context.Context, chainID types.ChainID, finalized eth.BlockRef) error

func (*UpdatesFrontend) UpdateLocalSafe ¶ added in v1.9.5

func (u *UpdatesFrontend) UpdateLocalSafe(ctx context.Context, chainID types.ChainID, derivedFrom eth.BlockRef, lastDerived eth.BlockRef) error

func (*UpdatesFrontend) UpdateLocalUnsafe ¶ added in v1.9.5

func (u *UpdatesFrontend) UpdateLocalUnsafe(ctx context.Context, chainID types.ChainID, head eth.BlockRef) error
