NAME

       YAML::PP::Schema::Tie::IxHash - (Deprecated) Schema for serializing ordered hashes

SYNOPSIS

           use YAML::PP;
           use Tie::IxHash;
           my $yp = YAML::PP->new( schema => [qw/ + Tie::IxHash /] );

           tie(my %ordered, 'Tie::IxHash');
           %ordered = (
               U => 2,
               B => 52,
           );

           my $yaml = $yp->dump_string(\%ordered);

           # Output:
           ---
           U: 2
           B: 52

DESCRIPTION

       This is deprecated. See the new option "preserve" in YAML::PP.

       This schema allows you to dump ordered hashes which are tied to Tie::IxHash.

       This code is pretty new and experimental.

       It is not yet implemented for loading yet, so for now you have to tie the hashes yourself.

       Examples:

       order
                   # Code
                   tie(my %order, 'Tie::IxHash');
                   %order = (
                       U => 2,
                       B => 52,
                       c => 64,
                       19 => 84,
                       Disco => 2000,
                       Year => 2525,
                       days_on_earth => 20_000,
                   );
                   \%order;

                   # YAML
                   ---
                   U: 2
                   B: 52
                   c: 64
                   19: 84
                   Disco: 2000
                   Year: 2525
                   days_on_earth: 20000

       order_blessed
                   # Code
                   tie(my %order, 'Tie::IxHash');
                   %order = (
                       U => 2,
                       B => 52,
                       c => 64,
                       19 => 84,
                       Disco => 2000,
                       Year => 2525,
                       days_on_earth => 20_000,
                   );
                   bless \%order, 'Order';

                   # YAML
