What is the ideal data structure to send task/data between the async context and a dedicated thread?

[cjwcommuny]

I read the blog Async: What is blocking?, which advocates the concept of employing a long running dedicated thread to handle blocking task. Consequently, this prompts the question - what would be the ideal data structure for passing tasks or data to the long running dedicated thread?

I have the following options:

1. Utilizing tokio::sync::mpsc::channel along with blocking_send/blocking_rcv in the dedicated thread.
2. Using crates like crossfire.

I would generally recommend using things from tokio::sync unless you have a good reason not to. So in this case, I recommend tokio::sync::mpsc over some other mpsc channel.
