    #   @param [Hash] options
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials. This can be an instance of any one of the
    #     following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::SharedCredentials` - Used for loading credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2 IMDS instance profile - When used by default, the timeouts are
    #       very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` to enable retries and extended
    #       timeouts.
    #
    #   @option options [required, String] :region

    # Creates an Application Load Balancer or a Network Load Balancer.
    #
    # When you create a load balancer, you can specify security groups,
    # public subnets, IP address type, and tags. Otherwise, you could do so
    # later using SetSecurityGroups, SetSubnets, SetIpAddressType, and
    # AddTags.
    #
    # To create listeners for your load balancer, use CreateListener. To
    # describe your current load balancers, see DescribeLoadBalancers. When
    # you are finished with a load balancer, you can delete it using
    # DeleteLoadBalancer.
    #
    # For limit information, see [Limits for Your Application Load
    # Balancer][1] in the *Application Load Balancers Guide* and [Limits for
    # Your Network Load Balancer][2] in the *Network Load Balancers Guide*.
    #
    # This operation is idempotent, which means that it completes at most
    # one time. If you attempt to create multiple load balancers with the
    # same settings, each call succeeds.
    #
    # For more information, see [Application Load Balancers][3] in the
    # *Application Load Balancers Guide* and [Network Load Balancers][4] in
    # the *Network Load Balancers Guide*.

    #   \[Network Load Balancers\] You can specify subnets from one or more
    #   Availability Zones.
    #
    # @option params [Array<Types::SubnetMapping>] :subnet_mappings
    #   The IDs of the public subnets. You can specify only one subnet per
    #   Availability Zone. You must specify either subnets or subnet mappings.
    #
    #   \[Application Load Balancers\] You must specify subnets from at least
    #   two Availability Zones. You cannot specify Elastic IP addresses for
    #   your subnets.
    #
    #   \[Network Load Balancers\] You can specify subnets from one or more
    #   Availability Zones. You can specify one Elastic IP address per subnet.
    #
    # @option params [Array<String>] :security_groups
    #   \[Application Load Balancers\] The IDs of the security groups for the
    #   load balancer.
    #
    # @option params [String] :scheme
    #   The nodes of an Internet-facing load balancer have public IP
    #   addresses. The DNS name of an Internet-facing load balancer is
    #   publicly resolvable to the public IP addresses of the nodes.
    #   Therefore, Internet-facing load balancers can route requests from
    #   clients over the internet.
    #
    #   The nodes of an internal load balancer have only private IP addresses.
    #   The DNS name of an internal load balancer is publicly resolvable to
    #   the private IP addresses of the nodes. Therefore, internal load
    #   balancers can only route requests from clients with access to the VPC
    #   for the load balancer.
    #
    #   The default is an Internet-facing load balancer.
    #
    # @option params [Array<Types::Tag>] :tags
    #   One or more tags to assign to the load balancer.
    #
    # @option params [String] :type
    #   The type of load balancer. The default is `application`.
    #
    # @option params [String] :ip_address_type
    #   \[Application Load Balancers\] The type of IP addresses used by the
    #   subnets for your load balancer. The possible values are `ipv4` (for
    #   IPv4 addresses) and `dualstack` (for IPv4 and IPv6 addresses).
    #   Internal load balancers must use `ipv4`.

    # @option params [required, Array<Types::RuleCondition>] :conditions
    #   The conditions. Each rule can include zero or one of the following
    #   conditions: `http-request-method`, `host-header`, `path-pattern`, and
    #   `source-ip`, and zero or more of the following conditions:
    #   `http-header` and `query-string`.
    #
    # @option params [required, Integer] :priority
    #   The rule priority. A listener can't have multiple rules with the same
    #   priority.
    #
    # @option params [required, Array<Types::Action>] :actions
    #   The actions. Each rule must include exactly one of the following types
    #   of actions: `forward`, `fixed-response`, or `redirect`.
    #
    #   If the action type is `forward`, you specify a target group. The
    #   protocol of the target group must be HTTP or HTTPS for an Application
    #   Load Balancer. The protocol of the target group must be TCP, TLS, UDP,
    #   or TCP\_UDP for a Network Load Balancer.
    #
    #   \[HTTPS listeners\] If the action type is `authenticate-oidc`, you
    #   authenticate users through an identity provider that is OpenID Connect
    #   (OIDC) compliant.
    #
    #   \[HTTPS listeners\] If the action type is `authenticate-cognito`, you
    #   authenticate users through the user pools supported by Amazon Cognito.
    #
    #   \[Application Load Balancer\] If the action type is `redirect`, you
    #   redirect specified client requests from one URL to another.
    #
    #   \[Application Load Balancer\] If the action type is `fixed-response`,
    #   you drop specified client requests and return a custom HTTP response.

    #   and must not begin or end with a hyphen.
    #
    # @option params [String] :protocol
    #   The protocol to use for routing traffic to the targets. For

    #   target is a Lambda function, this parameter does not apply.
    #
    # @option params [String] :vpc_id
    #   The identifier of the virtual private cloud (VPC). If the target is a
    #   Lambda function, this parameter does not apply.
    #
    # @option params [String] :health_check_protocol
    #   The protocol the load balancer uses when performing health checks on
    #   targets. For Application Load Balancers, the default is HTTP. For
    #   Network Load Balancers, the default is TCP. The TCP protocol is
    #   supported for health checks only if the protocol of the target group
    #   is TCP, TLS, UDP, or TCP\_UDP. The TLS, UDP, and TCP\_UDP protocols
    #   are not supported for health checks.
    #
    # @option params [String] :health_check_port
    #   The port the load balancer uses when performing health checks on
    #   targets. The default is `traffic-port`, which is the port on which
    #   each target receives traffic from the load balancer.
    #
    # @option params [Boolean] :health_check_enabled
    #   Indicates whether health checks are enabled. If the target type is
    #   `lambda`, health checks are disabled by default but can be enabled. If
    #   the target type is `instance` or `ip`, health checks are always
    #   enabled and cannot be disabled.
    #
    # @option params [String] :health_check_path
    #   \[HTTP/HTTPS health checks\] The ping path that is the destination on
    #   the targets for health checks. The default is /.
    #
    # @option params [Integer] :health_check_interval_seconds
    #   The approximate amount of time, in seconds, between health checks of
    #   an individual target. For HTTP and HTTPS health checks, the range is
    #   5–300 seconds. For TCP health checks, the supported values are 10 and
    #   30 seconds. If the target type is `instance` or `ip`, the default is
    #   30 seconds. If the target type is `lambda`, the default is 35 seconds.
    #
    # @option params [Integer] :health_check_timeout_seconds
    #   The amount of time, in seconds, during which no response from a target
    #   means a failed health check. For target groups with a protocol of HTTP
    #   or HTTPS, the default is 5 seconds. For target groups with a protocol
    #   of TCP or TLS, this value must be 6 seconds for HTTP health checks and
    #   10 seconds for TCP and HTTPS health checks. If the target type is
    #   `lambda`, the default is 30 seconds.
    #
    # @option params [Integer] :healthy_threshold_count
    #   The number of consecutive health checks successes required before
    #   considering an unhealthy target healthy. For target groups with a
    #   protocol of HTTP or HTTPS, the default is 5. For target groups with a
    #   protocol of TCP or TLS, the default is 3. If the target type is
    #   `lambda`, the default is 5.
    #
    # @option params [Integer] :unhealthy_threshold_count
    #   The number of consecutive health check failures required before
    #   considering a target unhealthy. For target groups with a protocol of
    #   HTTP or HTTPS, the default is 2. For target groups with a protocol of
    #   TCP or TLS, this value must be the same as the healthy threshold
    #   count. If the target type is `lambda`, the default is 2.
    #
    # @option params [Types::Matcher] :matcher
    #   \[HTTP/HTTPS health checks\] The HTTP codes to use when checking for a
    #   successful response from a target.
    #
    # @option params [String] :target_type

    #
    # @option params [required, String] :listener_arn
    #   The Amazon Resource Name (ARN) of the listener.
    #
    # @option params [Integer] :port
    #   The port for connections from clients to the load balancer.
    #
    # @option params [String] :protocol
    #   The protocol for connections from clients to the load balancer.
    #   Application Load Balancers support the HTTP and HTTPS protocols.
    #   Network Load Balancers support the TCP, TLS, UDP, and TCP\_UDP
    #   protocols.
    #
    # @option params [String] :ssl_policy
    #   \[HTTPS and TLS listeners\] The security policy that defines which
    #   protocols and ciphers are supported. For more information, see
    #   [Security Policies][1] in the *Application Load Balancers Guide*.

    #
    # @option params [Array<Types::Certificate>] :certificates
    #   \[HTTPS and TLS listeners\] The default certificate for the listener.
    #   You must provide exactly one certificate. Set `CertificateArn` to the
    #   certificate ARN but do not set `IsDefault`.
    #
    #   To create a certificate list, use AddListenerCertificates.
    #
    # @option params [Array<Types::Action>] :default_actions
    #   The actions for the default rule. The rule must include one forward
    #   action or one or more fixed-response actions.
    #
    #   If the action type is `forward`, you specify a target group. The
    #   protocol of the target group must be HTTP or HTTPS for an Application
    #   Load Balancer. The protocol of the target group must be TCP, TLS, UDP,
    #   or TCP\_UDP for a Network Load Balancer.
    #
    #   \[HTTPS listeners\] If the action type is `authenticate-oidc`, you
    #   authenticate users through an identity provider that is OpenID Connect
    #   (OIDC) compliant.
    #
    #   \[HTTPS listeners\] If the action type is `authenticate-cognito`, you
    #   authenticate users through the user pools supported by Amazon Cognito.
    #
    #   \[Application Load Balancer\] If the action type is `redirect`, you
    #   redirect specified client requests from one URL to another.
    #
    #   \[Application Load Balancer\] If the action type is `fixed-response`,
    #   you drop specified client requests and return a custom HTTP response.

    # Polls an API operation until a resource enters a desired state.
    #
    # ## Basic Usage
    #
    # A waiter will call an API operation until:
    #
    # * It is successful
    # * It enters a terminal state
    # * It makes the maximum number of attempts
    #
    # In between attempts, the waiter will sleep.
    #
    #     # polls in a loop, sleeping between attempts
    #     client.wait_until(waiter_name, params)
    #
    # ## Configuration
    #
    # You can configure the maximum number of polling attempts, and the
    # delay (in seconds) between each polling attempt. You can pass
    # configuration as the final arguments hash.
    #
    #     # poll for ~25 seconds
    #     client.wait_until(waiter_name, params, {
    #       max_attempts: 5,
    #       delay: 5,
    #     })
    #
    # ## Callbacks
    #
    # You can be notified before each polling attempt and before each
    # delay. If you throw `:success` or `:failure` from these callbacks,
    # it will terminate the waiter.
    #
    #     started_at = Time.now
    #     client.wait_until(waiter_name, params, {
    #
    #       # disable max attempts
    #       max_attempts: nil,
    #
    #       # poll for 1 hour, instead of a number of attempts
    #       before_wait: -> (attempts, response) do
    #         throw :failure if Time.now - started_at > 3600
    #       end
    #     })
    #
    # ## Handling Errors
    #
    # When a waiter is unsuccessful, it will raise an error.
    # All of the failure errors extend from
    # {Aws::Waiters::Errors::WaiterFailed}.
    #
    #     begin
    #       client.wait_until(...)
    #     rescue Aws::Waiters::Errors::WaiterFailed
    #       # resource did not enter the desired state in time
    #     end

    # The following table lists the valid waiter names, the operations they call,
    # and the default `:delay` and `:max_attempts` values.
