# @api private
#
# This class provides an abstract way to trigger resolved.
# Each parameters correspond to resolved.conf(5):
# https://www.freedesktop.org/software/systemd/man/resolved.conf.html
#
# @param ensure
# The state that the ``resolved`` service should be in
#
# @param dns
# A space-separated list of IPv4 and IPv6 addresses to use as system DNS servers.
# DNS requests are sent to one of the listed DNS servers in parallel to suitable
# per-link DNS servers acquired from systemd-networkd.service(8) or set at runtime
# by external applications. requires puppetlabs-inifile
#
# @param fallback_dns
# A space-separated list of IPv4 and IPv6 addresses to use as the fallback DNS
# servers. Any per-link DNS servers obtained from systemd-networkd take
# precedence over this setting. requires puppetlabs-inifile
#
# @param domains
# A space-separated list of domains host names or IP addresses to be used
# systemd-resolved take precedence over this setting.
#
# @param llmnr
# Takes a boolean argument or "resolve".
#
# @param multicast_dns
# Takes a boolean argument or "resolve".
#
# @param dnssec
# Takes a boolean argument or "allow-downgrade".
#
# @param dnsovertls
# Takes a boolean argument or "opportunistic" or "no"
#
# @param cache
# Takes a boolean argument or "no-negative".
#
# @param dns_stub_listener
# Takes a boolean argument or one of "udp" and "tcp".
#
# @param use_stub_resolver
# Takes a boolean argument. When "false" (default) it uses /var/run/systemd/resolve/resolv.conf
# as /etc/resolv.conf. When "true", it uses /var/run/systemd/resolve/stub-resolv.conf
