Function kvarn_signal::unix::start_at

pub async fn start_at(
    handler: impl Fn(Vec<u8>) -> Pin<Box<dyn Future<Output = HandlerResponse>>> + 'static,
    path: impl AsRef<Path> + Send + Sync + 'static
) -> (bool, UnboundedSender<bool>)

Available on Unix only.

Starts an [UnixListener] at path with handler receiving messages.

This starts a new task, and so the future resolves quickly.

The handler gets the data from the request, and should return whether to close the listener and the data to send back.

handler is guaranteed to be inside an async Tokio context - you can use e.g. [tokio::spawn].

Return value

Returns true if we removed an existing socket, false otherwise. The removed socket might be live or a leftover from a previous call to this (or any other UNIX socket creation).

The sender can be used to signal we need to close (if true is sent)
