    # @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) {|instance| instance.state.name == 'running' }
    #
    # ## 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(...)

    #   * `owner-id` - The ID of the AWS account that owns the snapshot.
    #
    #   * `progress` - The progress of the snapshot, as a percentage (for
    #     example, 80%).
    #
    #   * `snapshot-id` - The snapshot ID.
    #
    #   * `start-time` - The time stamp when the snapshot was initiated.
    #
    #   * `status` - The status of the snapshot (`pending` \| `completed` \|
    #     `error`).
    #
    #   * `tag`\:&lt;key&gt; - The key/value combination of a tag assigned to
    #     the resource. Use the tag key in the filter name and the tag value
    #     as the filter value. For example, to find all resources that have a
    #     tag with the key `Owner` and the value `TeamA`, specify `tag:Owner`
    #     for the filter name and `TeamA` for the filter value.
    #
    #   * `tag-key` - The key of a tag assigned to the resource. Use this
    #     filter to find all resources assigned a tag with a specific key,
    #     regardless of the tag value.
    #
    #   * `volume-id` - The ID of the volume the snapshot is for.
    #
    #   * `volume-size` - The size of the volume, in GiB.

    #   The IDs of the AWS accounts that can create volumes from the snapshot.
    # @option options [Array<String>] :snapshot_ids
    #   The snapshot IDs.

    #   If you have the required permissions, the error response is
    #   `DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.
