I would like to know what is the difference between tokio::task and futures::task.
Are both doing the same? If yes, which one should be preferred?

The tokio::task
module contains utilities for spawning tasks on the Tokio runtime.
The futures::task
is not really comparable to tokio::task
. It is better to compare it to std::task
, which mainly contains utilities for building wakers useful when manually implement the Future
trait on your own types. It also has a Spawn
trait, which I have never seen used.
You should use tokio::task
if you want to spawn tasks on the Tokio runtime. You should use futures::task
(or std::task
) if you are manually implementing Future
(or e.g. Stream
) and need special wakers.
