type Ledger

type Ledger interface {
	// GetBlockchainInfo returns basic info about blockchain
	GetBlockchainInfo() (*common.BlockchainInfo, error)
	// GetBlockByNumber returns block at a given height
	// blockNumber of  math.MaxUint64 will return last block
	GetBlockByNumber(blockNumber uint64) (*common.Block, error)
	// GetBlocksIterator returns an iterator that starts from `startBlockNumber`(inclusive).
	// The iterator is a blocking iterator i.e., it blocks till the next block gets available in the ledger
	// ResultsIterator contains type BlockHolder
	GetBlocksIterator(startBlockNumber uint64) (ResultsIterator, error)
	// Close closes the ledger
	Close()
}

	GetBookmarkAndClose() string
}

type ResultsIterator

type ResultsIterator interface {
	// Next returns the next item in the result set. The `QueryResult` is expected to be nil when
	// the iterator gets exhausted

	// Close releases resources occupied by the iterator
	Close()
}
