NAME

6       YAML::PP::Schema::Tie::IxHash - (Deprecated) Schema for serializing
7       ordered hashes
8

SYNOPSIS

10           use YAML::PP;
11           use Tie::IxHash;
12           my $yp = YAML::PP->new( schema => [qw/ + Tie::IxHash /] );
13
14           tie(my %ordered, 'Tie::IxHash');
15           %ordered = (
16               U => 2,
17               B => 52,
18           );
19
20           my $yaml = $yp->dump_string(\%ordered);

23           # Output:

DESCRIPTION

29       This is deprecated. See the new option "preserve" in YAML::PP.
30
31       This schema allows you to dump ordered hashes which are tied to
32       Tie::IxHash.
33
34       This code is pretty new and experimental.
35
36       It is not yet implemented for loading yet, so for now you have to tie
37       the hashes yourself.
38
39       Examples:
40
41       order
42                   # Code
43                   tie(my %order, 'Tie::IxHash');
44                   %order = (
45                       U => 2,
46                       B => 52,
47                       c => 64,
48                       19 => 84,
49                       Disco => 2000,
50                       Year => 2525,
51                       days_on_earth => 20_000,
52                   );
