    # @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(...)
    #     rescue Aws::Waiters::Errors::WaiterFailed
    #       # resource did not enter the desired state in time

    #
    # @raise [Aws::Waiters::Errors::FailureStateError] Raised when the waiter 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 encountered
    #   while polling for a resource that is not expected.
