=head1 NAME
Dancer::Serializer::YAML - serializer for handling YAML data
=head1 VERSION
version 1.3202
=head1 SYNOPSIS
=head1 DESCRIPTION
This class is an interface between Dancer's serializer engine abstraction layer
and the L<YAML> (or L<YAML::XS>) module.
In order to use this engine, use the template setting:
serializer: YAML
This can be done in your config.yml file or directly in your app code with the
B<set> keyword. This serializer will also be used when the serializer is set
to B<mutable> and the correct Accept headers are supplied.
By default, the module L<YAML> will be used to serialize/deserialize data and
the application configuration files. This can be changed via the
configuration:
engines:
YAML:
module: YAML::XS
Note that if you want all configuration files to be read using C<YAML::XS>,
that configuration has to be set via application code:
config->{engines}{YAML}{module} = 'YAML::XS';
=head1 METHODS
=head2 serialize
Serialize a data structure to a YAML structure.
=head2 deserialize
Deserialize a YAML structure to a data structure
=head2 content_type
Return 'text/x-yaml'
