METHODS

msgpack($OBJECT)

Encode perl object (scalar, hash, array) to octets.

msgunpack($OCTETS[, $UTF8])

Decide octets to perl object. Return perl object and tail of input string.
If $UTF8 is true, msgunpack will decode utf8-strings.

true and false

Protocol supports "true" and "false" statements. msgunpack unpacks them to 1 and 0.
If You want to pack "true" You can use DR::Tarantool::MsgPack::Bool:
    use DR::Tarantool::MsgPack 'msgpack';
    my $to_pack = { a => DR::Tarantool::MsgPack::Bool->new(0) };
    my $pkt = msgpack($to_pack);
