+/// A macro for creating a component server, determined by the component's execution mode.
+/// Returns a remote server if the component is run with remote configuration, otherwise None.
+///
+/// # Arguments
+///
+/// * $execution_mode - A reference to the component's execution mode, i.e., type
+///   &ComponentExecutionMode.
+/// * $local_client - The local client to be used for the remote server initialization if the
+///   execution mode is enabled(Remote).
+/// * $config - The remote server configuration.
+///
+/// # Returns
+///
+/// An Option<Box<RemoteComponentServer<LocalClientType, RequestType, ResponseType>>> containing the
+/// server if the execution mode is enabled(Remote), or None if the execution mode is Disabled.
+///
+/// # Example
+///
+/// ```rust,ignore
+/// let batcher_remote_server = create_remote_server!(
+///     &config.components.batcher.execution_mode,
+///     local_client,
+///     config.remote_server_config
+/// );
+/// match batcher_remote_server {
+///     Some(server) => println!("Remote server created: {:?}", server),
+///     None => println!("Remote server not created because the execution mode is not remote."),
+/// }
