NAME

Dancer2::Core::Role::Serializer - Role for Serializer engines

VERSION

version 0.143000

DESCRIPTION

Any class that consumes this role will be able to be used as a serializer under Dancer2.

In order to implement this role, the consumer must implement the methods serialize, deserialize and loaded, and should define the content_type attribute value.

ATTRIBUTES

error

The error string in case the serializer is in error state.

content_type

The content type of the object after being serialized. For example, a JSON serializer would have a application/json content type defined.

METHODS

has_error

A predicate to check whether the serializer is in error state.

serialize($content, [\%options])

The serialize method need to be implemented by the consumer. It receives the serializer class object and a reference to the object to be serialized. Should return the object after being serialized, in the content type defined by the content_type attribute.

A third optional argument is a hash reference of options to the serializer.

The serialize method must return bytes and therefore has to handle any encoding.

deserialize($content, [\%options])

The inverse method of serialize. Receives the serializer class object and a string that should be deserialized. The method should return a reference to the deserialized Perl data structure.

A third optional argument is a hash reference of options to the serializer.

The deserialize method receives encoded bytes and must therefore handle any decoding required.

loaded

This method should return a boolean true value if the serializer is able to work. This method might verify the existence of some Perl module or some other detail. If everything needed for the serializer to work is present the method returns a true value. If not, returns a false value.
