The package describes all spaces that You use. It supports the following field types:
- standard tarantool types.
- the same as STR, but string will be utf8-decoded after extracting from database.
- the same as NUM and NUM64, but contain signed values.
- the filed will be encoded by JSON::XS before inserting and decoded after extracting from database.
my $spaces = DR::Tarantool::Spaces->new( $spaces );
Returns space object by number or name.
my $space = $spaces->space('name');
my $space = $spaces->space(0);
packs one field before making database request
my $field = $spaces->pack_field('space', 'field', $data);
unpacks one field after extracting data from database
my $field = $spaces->unpack_field('space', 'field', $data);
packs tuple before making database request
my $t = $spaces->pack_tuple('space', [ 1, 2, 3 ]);
unpacks tuple after extracting data from database
my $t = $spaces->unpack_tuple('space', \@fields);
