- Rewrite noop_waker with items from the new API and replaces
LocalWaker with Waker.
- Bump the minimum required version for `tokio-async-await` to
1.34.0-nightly.
- `Unpin` was added to std prelude.
- Add `cargo check` to .travis.yml
Fixes: #908
* async-await: fix README example dependencies
As per commit "async-await: track nightly changes (#661)" ( commit
2f690d30bc061a8595744e34fde371882b676a86)
> The `tokio-async-await` crate is no longer a facade. Instead, the
> `tokio` crate provides a feature flag to enable async/await support.
Ensure the example in the async-await README file also works by
correctly declaring this updated dependency
* async-await: remove unnecessary 'edition' declaration from README
As the "edition" feature was stabilized in rust v1.30 and async-await
specifies that the nightly toolchain must be used, remove the use of the
"edition" feature gate since it is enabled by default.
This patch adds experimental async/await support to Tokio. It does this
by adding feature flags to existing libs only where necessary in order
to add nightly specific code (mostly `Unpin` implementations). It then
provides a new crate: `tokio-async-await` which is a shim layer on top
of `tokio`.
The `tokio-async-await` crate is expected to look exactly like `tokio`
does, but with async / await support. This strategy reduces the amount
of cfg guarding in the main libraries.
This patch also adds `tokio-channel`, which is copied from futures-rs
0.1 and adds the necessary `Unpin` implementations. In general, futures
0.1 is mostly unmaintained, so it will make sense for Tokio to take over
maintainership of key components regardless of async / await support.
