# <%= render template: 'articles/show' %>
class Template
# Initialize a template
#
# @param view [Hanami::View] the current view
# @param options [Hash] the rendering informations
# @option options [Symbol] :format the current format
# @option options [Hash] :locals the set of objects available within
# the rendering context

def initialize(view, options)
@view, @options = view, options

# @return [String] the output of the rendering process.

# @raise [Hanami::View::MissingTemplateError] if template can't be found
