	...

	my $str = dump_to_row($some_structure);


=head1 DESCRIPTION

NetSDS::Util::Struct module contains different utilities for data structures processing.

=head1 EXPORTED METHODS

=over

=item B<dump_to_string(...)>

Returns cleaned dump to scalar.

#***********************************************************************

=item B<dump_to_row(...)>

Returns cleaned dump to scalar.

=cut

	my ($data) = @_;

		return $data;

#***********************************************************************

=item B<arrays_to_hash($keys_ref, $values_ref)> - translate arrays to hash

Parameters: references to keys array and values array

Return: hash

If @$keys_ref is longer than @$values_ref - rest of keys filled with
C<undef> values.

If @$keys_ref is shorter than @$values_ref - rest of values are discarded.

If any of parameters isn't array reference then C<undef> will return.

Example:

	my %h = array2hash(['fruit','animal'], ['apple','horse']);

Result should be a hash:

	(
		fruit => 'apple',
		animal => 'horse'
	)

=cut

#-----------------------------------------------------------------------
sub arrays_to_hash {
	my ( $keys_ref, $values_ref ) = @_;

	return undef unless ( is_ref_array($keys_ref) and is_ref_array($values_ref) );

	my %h = ();

	for ( my $i = 0 ; $i < scalar(@$keys_ref) ; $i++ ) {
		$h{ $keys_ref->[$i] } = defined( $values_ref->[$i] ) ? $values_ref->[$i] : undef;
	}

	return %h;
}

#***********************************************************************

=item B<merge_hash($target, $source)> - merge two hashes

Parameters: references to target and source hashes.

This method adds source hash to target one and return value as a result.

=cut

#-----------------------------------------------------------------------
sub merge_hash {
	my ( $trg, $src ) = @_;

	while ( my ( $key, $val ) = each( %{$src} ) ) {
		if ( is_ref_hash($val) and is_ref_hash( $trg->{$key} ) ) {
