Iterator for query results.

// Iterator for query results.
type Iterator interface {
	// Next advances the iterator to the next value, which will then be available through
	// the Result method. It returns false if no further advancement is possible, or if an
	// error was encountered during iteration.  Err should be consulted to distinguish
	// between the two cases.
	Next(ctx context.Context) bool
	// Results returns the current result. The type depends on the collation mode of the query.
	Result() interface{}
	// Err returns any error that was encountered by the Iterator.
	Err() error
	// Close the iterator and do internal cleanup.
	Close() error
}

// Collation of results.
