=head1 NAME
L<Data::Session::ID::UUID64> - A persistent session manager
=head1 Synopsis
See L<Data::Session> for details.
=head1 Description
L<Data::Session::ID::UUID64> allows L<Data::Session> to generate session ids using L<Data::UUID>.
To use this module do this:
=over 4
=item o Specify an id generator of type UUID64, as Data::Session -> new(type => '... id:UUID64 ...')
=back
Note: The uuid will be 24 (sic) bytes because that's the number of bytes in a UUID64 digest.
See scripts/digest.pl.
=head1 Case-sensitive Options
See L<Data::Session/Case-sensitive Options> for important information.
=head1 Method: new()
Creates a new object of type L<Data::Session::ID::UUID64>.
C<new()> takes a hash of key/value pairs, some of which might mandatory. Further, some combinations
might be mandatory.
The keys are listed here in alphabetical order.
They are lower-case because they are (also) method names, meaning they can be called to set or get
the value at any time.
=over 4
=item o verbose => $integer
Print to STDERR more or less information.
Typical values are 0, 1 and 2.
This key is normally passed in as Data::Session -> new(verbose => $integer).
This key is optional.
=back
=head1 Method: generate()
Generates the next session id, or dies if it can't.
The algorithm is Data::UUID -> new -> create_b64.
Returns the new id.
Warning: You should never try to use 'driver:File;id:UUID64;...', since the ids generated by
this module sometimes contain '/', which the code forbids to be part of a file name.
=head1 Method: id_length()
Returns 24 (sic) because that's the number of bytes in a UUID64 digest.
This can be used to generate the SQL to create the sessions table.
See scripts/digest.pl.
