    # @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(...)
    #     rescue Aws::Waiters::Errors::WaiterFailed

    #     end
    #

    #   terminates because the waiter has entered a state that it will not
    #   transition out of, preventing success.

    #   yet successful.
    #
    # @raise [Aws::Waiters::Errors::UnexpectedError] Raised when an error is

    #   the destination Region in a `PresignedUrl` parameter, where it is
    #   required.
    #
    #   The snapshot copy is sent to the regional endpoint that you sent the
    #   HTTP request to (for example, `ec2.us-east-1.amazonaws.com`). With the
    #   CLI, this is specified using the `--region` parameter or the default

    #   is not enabled, enable encryption using this parameter. Otherwise,

    #   if you omit this parameter and encryption by default is not enabled.
    #   You cannot set this parameter to false. For more information, see

    #

    #   [1]: https://docs.aws.amazon.com/ebs/latest/userguide/ebs-encryption.html
    # @option options [String] :kms_key_id
    #   The identifier of the KMS key to use for Amazon EBS encryption. If
    #   this parameter is not specified, your KMS key for Amazon EBS is used.
    #   If `KmsKeyId` is specified, the encrypted state must be `true`.
    #
    #   You can specify the KMS key using any of the following:
    #
    #   * Key ID. For example, 1234abcd-12ab-34cd-56ef-1234567890ab.
    #
    #   * Key alias. For example, alias/ExampleAlias.
    #
    #   * Key ARN. For example,
    #     arn:aws:kms:us-east-1:012345678910:key/1234abcd-12ab-34cd-56ef-1234567890ab.
    #
    #   * Alias ARN. For example,
    #     arn:aws:kms:us-east-1:012345678910:alias/ExampleAlias.
    #
    #   Amazon Web Services authenticates the KMS key asynchronously.

    #   unencrypted snapshots. For more information, see [Query requests][1].
    #
    #   The `PresignedUrl` should use the snapshot source endpoint, the
    #   `CopySnapshot` action, and include the `SourceRegion`,
    #   `SourceSnapshotId`, and `DestinationRegion` parameters. The
    #   `PresignedUrl` must be signed using Amazon Web Services Signature
    #   Version 4. Because EBS snapshots are stored in Amazon S3, the signing
    #   algorithm for this parameter uses the same logic that is described in
    #   [ Authenticating Requests: Using Query Parameters (Amazon Web Services
    #   Signature Version 4)][2] in the *Amazon S3 API Reference*. An invalid
    #   or improperly signed `PresignedUrl` will cause the copy operation to
    #   fail asynchronously, and the snapshot will move to an `error` state.
