There are no Structures in Perl.  As far as hash sizes, the follwoing is
about all you can do :

perldata manpage

  Scalar Values

...

    If you evaluate a hash in scalar context, it returns false if the hash is
    empty. If there are any key/value pairs, it returns true; more precisely,
    the value returned is a string consisting of the number of used buckets and
    the number of allocated buckets, separated by a slash. This is pretty much
    useful only to find out whether Perl's internal hashing algorithm is
    performing poorly on your data set. For example, you stick 10,000 things in
    a hash, but evaluating %HASH in scalar context reveals "1/16", which means
    only one out of sixteen buckets has been touched, and presumably contains
    all 10,000 of your items. This isn't supposed to happen.

What does that have to do with hashes ?  You would need to serialize
the hash to send it on a socket and then you can easily determine the
length.  Check Storable module for serializing data.
