Streams CountryInstance records from the API as a generator stream.
This operation lazily loads records as efficiently as possible until the limit
is reached.
The results are returned as a generator, so this operation is memory efficient.

:param unicode iso_code: Filter to retrieve the country permissions by specifying the ISO country code
:param unicode continent: Filter to retrieve the country permissions by specifying the continent
:param unicode country_code: Country code filter
:param bool low_risk_numbers_enabled: Filter to retrieve the country permissions with dialing to low-risk numbers enabled
:param bool high_risk_special_numbers_enabled: Filter to retrieve the country permissions with dialing to high-risk special service numbers enabled
:param bool high_risk_tollfraud_numbers_enabled: Filter to retrieve the country permissions with dialing to high-risk toll fraud numbers enabled
:param int limit: Upper limit for the number of records to return. stream()
                  guarantees to never return more than limit.  Default is no limit
:param int page_size: Number of records to fetch per request, when not set will use
                      the default value of 50 records.  If no page_size is defined
                      but a limit is defined, stream() will attempt to read the
                      limit with the most efficient page size, i.e. min(limit, 1000)

:returns: Generator that will yield up to limit results
:rtype: list[twilio.rest.voice.v1.dialing_permissions.country.CountryInstance]
