Is there a list of what async primitive MUST be used with a tokio runtime?

Most of Futures can be polled with any runtime, but some of the primitives, like tokio::net::TcpListener, tokio::sync::oneshot must be used with tokio runtime since they cooperate with the TLS handle.

The things in tokio::sync do not need a runtime, and everything else needs a Tokio runtime.

You mention the oneshot channel, but it does not depend on the runtime. Yes, it will access the Tokio's TLS storage to interact with cooperative scheduling, but this is optional, and the channel will still work if the TLS is unavailable.

This is the answer I want to know. And good to know for the details of oneshot channel. Thank you!
