Rem will remove a deltas by block ID.

type Engine

type Engine struct {
	psEvents.Noop              // satisfy protocol events consumer interface
	notifications.NoopConsumer // satisfy the FinalizationConsumer interface
	// contains filtered or unexported fields
}

An Engine receives and saves incoming blocks.

) (*Engine, error)

func (*Engine) BlockProcessable added in v0.10.0

func (e *Engine) BlockProcessable(b *flow.Header)

BlockProcessable handles the new verified blocks (blocks that have passed consensus validation) received from the consensus nodes Note: BlockProcessable might be called multiple times for the same block.

func (*Engine) Done

func (e *Engine) Done() <-chan struct{}

Done returns a channel that will close when the engine has successfully stopped.

func (*Engine) ExecuteScriptAtBlockID

func (e *Engine) ExecuteScriptAtBlockID(ctx context.Context, script []byte, arguments [][]byte, blockID flow.Identifier) ([]byte, error)

func (*Engine) GetAccount

func (e *Engine) GetAccount(ctx context.Context, addr flow.Address, blockID flow.Identifier) (*flow.Account, error)

func (*Engine) OnCollection

func (e *Engine) OnCollection(originID flow.Identifier, entity flow.Entity)

OnCollection is a callback for handling the collections requested by the collection requester.

func (*Engine) Process

func (e *Engine) Process(originID flow.Identifier, event interface{}) error

func (*Engine) ProcessLocal

func (e *Engine) ProcessLocal(event interface{}) error

ProcessLocal processes an event originating on the local node.

func (*Engine) Ready

func (e *Engine) Ready() <-chan struct{}

Ready returns a channel that will close when the engine has successfully started.

func (*Engine) Submit

func (e *Engine) Submit(originID flow.Identifier, event interface{})

Submit submits the given event from the node with the given origin ID for processing in a non-blocking manner. It returns instantly and logs a potential processing error internally when done.

func (*Engine) SubmitLocal

func (e *Engine) SubmitLocal(event interface{})

SubmitLocal submits an event originating on the local node.

type IngestRPC

type IngestRPC interface {

	// ExecuteScriptAtBlockID executes a script at the given Block id
	ExecuteScriptAtBlockID(ctx context.Context, script []byte, arguments [][]byte, blockID flow.Identifier) ([]byte, error)

	// GetAccount returns the Account details at the given Block id
	GetAccount(ctx context.Context, address flow.Address, blockID flow.Identifier) (*flow.Account, error)
}

IngestRPC represents the RPC calls that the execution ingest engine exposes to support the Access Node API calls

type Mempool

type Mempool struct {
	ExecutionQueue    *stdmap.Queues
	BlockByCollection *stdmap.BlockByCollections
}

func (*Mempool) Run

func (m *Mempool) Run(f func(blockByCollection *stdmap.BlockByCollectionBackdata, executionQueue *stdmap.QueuesBackdata) error) error
