=head1 NAME
Redis::Hash - tie Perl hashes to Redis hashes
=head1 VERSION
version 1.982
=head1 DESCRIPTION
Ties a Perl hash to Redis. Note that it doesn't use Redis Hashes, but
implements a fake hash using regular keys like "prefix:KEY".
If no C<prefix> is given, it will tie the entire Redis database as a hash.
Future versions will also allow you to use real Redis hash structures.
=head1 SYNOPSYS
## Create fake hash using keys like 'hash_prefix:KEY'
tie %my_hash, 'Redis::Hash', 'hash_prefix', @Redis_new_parameters;
## Treat the entire Redis database as a hash
tie %my_hash, 'Redis::Hash', undef, @Redis_new_parameters;
$value = $my_hash{$key};
$my_hash{$key} = $value;
@keys = keys %my_hash;
@values = values %my_hash;
%my_hash = reverse %my_hash;
%my_hash = ();
