NAME

       Tie::Hash::Indexed - Ordered hashes for Perl

SYNOPSIS

         use Tie::Hash::Indexed;

         tie my %hash, 'Tie::Hash::Indexed';

         %hash = ( I => 1, n => 2, d => 3, e => 4 );
         $hash{x} = 5;

         print keys %hash, "\n";    # prints 'Index'
         print values %hash, "\n";  # prints '12345'

DESCRIPTION

       Tie::Hash::Indexed is very similar to Tie::IxHash. However, it is written completely in XS and usually
       about twice as fast as Tie::IxHash. It's quite a lot faster when it comes to clearing or deleting entries
       from large hashes.  Currently, only the plain tying mechanism is supported.

ENVIRONMENT

   "THI_DEBUG_OPT"
       If Tie::Hash::Indexed is built with debugging support, you can use this environment variable to specify
       debugging options. Currently, the only useful values you can pass in are "d" or "all", which both enable
       debug output for the module.

PROBLEMS

       As the data of Tie::Hash::Indexed objects is hidden inside the XS implementation, cloning/serialization
       is problematic.  Tie::Hash::Indexed implements hooks for Storable, so cloning or serializing objects
       using Storable is safe.

       Tie::Hash::Indexed tries very hard to detect any corruption in its data at runtime. So if something goes
       wrong, you'll most probably receive an appropriate error message.

BUGS

       If you find any bugs, Tie::Hash::Indexed doesn't seem to build on your system or any of its tests fail,
       please use the CPAN Request Tracker at <http://rt.cpan.org/> to create a ticket for the module.
       Alternatively, just send a mail to <mhx@cpan.org>.
