Catman...alizer(3pm)

✨ Catman...alizer 💅

okay bestie, listen up 💖 this is the page for Catmandu::Serializer — it's living in the User Contributed Perl Documentation section of the manual (yes, a 3pm page, we love a Perl module moment 🎀).

---

🌸 NAME 🌸

Catmandu::Serializer — the base class for all the Catmandu Serializers. it's giving founding mother energy 👑

---

✨ SYNOPSIS ✨

here's the whole vibe, copy it exactly bestie, no cap:

package Catmandu::Serializer::Foo;

use Moo;

sub serialize {
    my ($self,$data) = @_;
    .. transform the data to a string and return it...
}

sub deserialize {
    my ($self,$string) = @_;
    ... transform the string into a perl hash ...
}

package MyPackage;

use Moo;

with 'Catmandu::Serializer';

package main;

my $pkg = MyPackage->new;

my $string = $pkg->serialize({ foo => 'bar' });
my $perl   = $pkg->deserialize($string);

# Using Catmandu::Serializer::Foo
my $pkg = MyPackage->new( serialization_format => 'Foo' );

my $string = $pkg->serialize({ foo => 'bar' });
my $perl   = $pkg->deserialize($string);

🦋 DESCRIPTION 🦋

so basically Catmandu::Serializer is a convenience class for yeeting Perl hashes over the wire 🌈 easily. like, without you having to instantiate a Catmandu::Importer and a Catmandu::Exporter — because those two are honestly more suited for processing IO streams, and that's just not the moment rn. iykyk 💅
