	Events flow.EventsList

	// TrieUpdate is the trie update generated by executing the collection
	// This includes a list of all registers updated during the execution
	TrieUpdate *ledger.TrieUpdate

	// TransactionResults are the results of executing the transactions in the collection
	// This includes all of the data from flow.TransactionResult, except that it uses a boolean
	// value to indicate if an error occurred instead of a full error message.
	TransactionResults []flow.LightTransactionResult
}

ChunkExecutionData represents the execution data of a chunk

type Downloader 

type Downloader interface {
	module.ReadyDoneAware
	ExecutionDataGetter
	ProcessedHeightRecorder
}

Downloader is used to download execution data blobs from the network via a blob service.

type DownloaderOption 

type DownloaderOption func(*downloader)

type ExecutionDataDBMode added in v0.37.1 

type ExecutionDataDBMode int

ExecutionDataDBMode controls which db type to use. 

const (
	// ExecutionDataDBModeBadger uses badger db
	ExecutionDataDBModeBadger ExecutionDataDBMode = iota + 1

	// ExecutionDataDBModePebble uses pebble db
	ExecutionDataDBModePebble
)

type ExecutionDataGetter interface {
	// Get gets the BlockExecutionData for the given root ID from the blobstore.
	// Expected errors during normal operations:
	// - BlobNotFoundError if some CID in the blob tree could not be found from the blobstore
	// - MalformedDataError if some level of the blob tree cannot be properly deserialized
	// - BlobSizeLimitExceededError if some blob in the blob tree exceeds the maximum allowed size
