    # @deprecated Use [Aws::EC2::Client] #wait_until instead
    #
    # Waiter polls an API operation until a resource enters a desired
    # state.
    #
    # @note The waiting operation is performed on a copy. The original resource
    #   remains unchanged.
    #
    # ## Basic Usage
    #
    # Waiter will polls until it is successful, it fails by
    # entering a terminal state, or until a maximum number of attempts
    # are made.
    #
    #     # polls in a loop until condition is true
    #     resource.wait_until(options) {|resource| condition}
    #
    # ## Example
    #
    #     instance.wait_until(max_attempts:10, delay:5) do |instance|
    #       instance.state.name == 'running'
    #     end
    #
    # ## Configuration
    #
    # You can configure the maximum number of polling attempts, and the
    # delay (in seconds) between each polling attempt. The waiting condition is
    # set by passing a block to {#wait_until}:
    #
    #     # poll for ~25 seconds
    #     resource.wait_until(max_attempts:5,delay:5) {|resource|...}
    #
    # ## 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
    #     # poll for 1 hour, instead of a number of attempts
    #     proc = Proc.new do |attempts, response|
    #       throw :failure if Time.now - started_at > 3600
    #     end
    #
    #       # disable max attempts
    #     instance.wait_until(before_wait:proc, max_attempts:nil) {...}
    #
    # ## Handling Errors
    #
    # When a waiter is successful, it returns the Resource. When a waiter
    # fails, it raises an error.
    #
    #     begin
    #       resource.wait_until(...)

    # @option options [Boolean] :enable_primary_ipv_6
    #   If you’re launching an instance into a dual-stack or IPv6-only subnet,
    #   you can enable assigning a primary IPv6 address. A primary IPv6
    #   address is an IPv6 GUA address associated with an ENI that you have
    #   enabled to use a primary IPv6 address. Use this option if an instance
    #   relies on its IPv6 address not changing. When you launch the instance,
    #   Amazon Web Services will automatically assign an IPv6 address
    #   associated with the ENI attached to your instance to be the primary
    #   IPv6 address. Once you enable an IPv6 GUA address to be a primary
    #   IPv6, you cannot disable it. When you enable an IPv6 GUA address to be
    #   a primary IPv6, the first IPv6 GUA will be made the primary IPv6
    #   address until the instance is terminated or the network interface is
    #   detached. If you have multiple IPv6 addresses associated with an ENI
    #   attached to your instance and you enable a primary IPv6 address, the
    #   first IPv6 GUA address associated with the ENI becomes the primary
    #   IPv6 address.
    # @option options [Types::InstanceNetworkPerformanceOptionsRequest] :network_performance_options
    #   Contains settings for the network performance options for the
    #   instance.

    # @option options [Array<Types::InstanceSecondaryInterfaceSpecificationRequest>] :secondary_interfaces
    #   The secondary interfaces to associate with the instance.
    # @option options [Boolean] :dry_run

    #   If you’re creating a network interface in a dual-stack or IPv6-only

    #   primary IPv6 address is an IPv6 GUA address associated with an ENI
    #   that you have enabled to use a primary IPv6 address. Use this option
    #   if the instance that this ENI will be attached to relies on its IPv6
    #   address not changing. Amazon Web Services will automatically assign an
    #   IPv6 address associated with the ENI attached to your instance to be
    #   the primary IPv6 address. Once you enable an IPv6 GUA address to be a
    #   primary IPv6, you cannot disable it. When you enable an IPv6 GUA
    #   address to be a primary IPv6, the first IPv6 GUA will be made the
    #   primary IPv6 address until the instance is terminated or the network
    #   interface is detached. If you have multiple IPv6 addresses associated

    #     filter to find all resources assigned a tag with a specific key,
