=head1 NAME
AnyEvent::Serialize - async serialize/deserialize function
=head1 SYNOPSIS
use AnyEvent::Serialize ':all';
use AnyEvent::Serialize 'serialize';
use AnyEvent::Serialize 'deserialize';
use AnyEvent::Serialize ... block_size => 666;
serialize $object, sub { ($str, $recursion_detected) = @_ };
deserialize $string, sub { my ($object, $error, $tail) = @_ }
=head1 DESCRIPTION
Sometimes You need to serialize/deserialize a lot of data. If You
do it using L<Data::Dumper> or B<eval> it can take You too much time.
This module splits (de)serialization process into fixed-size parts
and does this work in non-blocking mode.
This module uses L<Data::StreamSerializer> and L<Data::StreamDeserializer>
to serialize or deserialize Your data.
=head1 EXPORT
=head2 serialize($object, $result_callback)
Serializes Your object. When serialization is done it will call
B<$result_callback>. This callback receives two arguments:
=over
=item result string
=item flag if recursion is detected
=back
=head2 deserialize($str, $result_callback)
Deserializes Your string. When deserialization is done or an error is
detected it will call B<$result_callback>. This callback receives three
arguments:
=over
=item deserialized object
=item error string (if an error was occured)
=item undeserialized string tail
=back
=head1 BREAKING
You can break serialization/deserialization process if You save value that
is returned by functions L<serialize>/L<deserialize>. They return guards
if they are called in non-void context.
=head1 SEE ALSO
L<Data::StreamSerializer>, L<Data::StreamDeserializer>.
