# * body [Hash]:
# * Delimeter [String] - Delimiter specified for query
# * IsTruncated [Boolean] - Whether or not the listing is truncated
# * Marker [String]- Marker specified for query
# * MaxKeys [Integer] - Maximum number of keys specified for query
# * Name [String] - Name of the bucket
# * Prefix [String] - Prefix specified for query
# * CommonPrefixes [Array] - Array of strings for common prefixes
