NAME
       Dancer2::Core::Role::Headers - Role for handling headers


VERSION
       version 0.11


DESCRIPTION
       When a class consumes this role, it gets a "headers" attribute and all the helper methods to manipulate
       it.

       This logic is contained in this role in order to reuse the code between Dancer2::Core::Response and
       Dancer2::Core::Request objects.


ATTRIBUTES
   headers
       The attribute that store the headers in a HTTP::Headers object.

       That attribute coerces from ArrayRef and defaults to an empty HTTP::Headers instance.


METHODS
   header($name)
       Return the value of the given header, if present. If the header has multiple values, returns the list of
       values if called in list context, the first one if in scalar context.

   push_header
       Add the header no matter if it already exists or not.

           $self->push_header( 'X-Wing' => '1' );

       It can also be called with multiple values to add many times the same header with different values:

           $self->push_header( 'X-Wing' => 1, 2, 3 );

   headers_to_array
       Convert the "headers" attribute to an ArrayRef.
