Implementations

impl ResponseSlot

pub fn new(timeout_ms: Option<u64>) -> Self

Create a new ResponseSlot.

This will initialize the slot with a default error (NotSupported) and set up the notification system. The timeout_ms is an optional input in milisecs, the default timeout is 1000ms.

pub async fn get(&self) -> Result<Response, DiagError>

Get a response in a blocking manner. This will block forever until a response is available.

It waits for the notification to be triggered and then locks the Mutex to retrieve the response.

pub async fn wait_for_response(&self) -> Response

Get a response with a timeout. If no response is received within the timeout period, an error is returned.

This function uses tokio::select! to wait for either the notification or the timeout. If the timeout expires, it returns a Timeout error.

pub async fn update_response(&self, new_data: Vec<u8>)

Update the response data in the response slot and notify the waiting task.

This function is used to update the response after receiving new data. It creates a UdsFrame from the provided new_data and replaces the current response data. After updating, it notifies the waiting task that the response is ready.
