module OEmbed
  
  # A generic OEmbed-related Error. The OEmbed library does its best to capture all internal
  # errors and wrap them in an OEmbed::Error class so that the error-handling code in your
  # application can more easily identify the source of errors.
  #
  # The following Classes inherit from OEmbed::Error
  # * OEmbed::FormatNotSupported
  # * OEmbed::NotFound
  # * OEmbed::ParseError
  # * OEmbed::UnknownFormat
  # * OEmbed::UnknownResponse
  class Error < StandardError

    def to_s
