Method callback.

The call callback implement the operation on the method when it is added via Server::add_method_node().

Required Methods

fn call(&mut self, context: &mut MethodCallbackContext) -> MethodCallbackResult

Calls method.

This is called when a client wants to call the method. The input arguments are available, and the output arguments are expected to be returned, through the context argument. See MethodCallbackContext::input_arguments() and MethodCallbackContext::output_arguments_mut() for details.

Errors

This should return an appropriate error when the call is not possible. The underlying status code is forwarded to the client.
