module PuppetWebhook
  # Class object for parsing payloads from version control system webhook
  # services. This will parse content from the Rack::Request body (JSON) or
  # the Rack::Request params (Form data) into an OpenStruct object for use
  # by the Sinatra application.
  #
  # @example
  #   request.body.rewind
  #   data = PuppetWebhook::Parsers.new(request.env, request.body.read)
  #   data.params
  class Parsers
    # Public: Initialize the Parsers object
    #
    # @param [Sinatra::Request] request Rack request object to be parsed
    #
    # @return [PuppetWebhook::Parsers]

    # request header.

    # @return [OpenStruct]
