* upgrade to rand 0.7.0 (MSRV 1.32)
* upgrade to parking_lot 0.9.0
* Remove last non-dev dependency on rand crate (#1324)
Use std RandomState for XorShift seeding. This allows dropping _rand_
crate dep here, accept as a dev dependency for tests or benchmarks.
* increase CI MSRV to 1.31.0
* increase nightly for CI TSAN tests
* add TSAN suppressions for recent rand related updates
* make latest TSAN suppression patterns more general
* upgrade tempfile dev dep for common rand version
But avoid tempfile 3.2 for now, since history demonstrates it bumps
rand versions and MSRV in MINOR updates.
* update (dev dep) env_logger to latest 0.6
* reactor, threadpool: bump PATCH versions, doc links, change logs [ci-release]
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.
This also bumps a number of sub crates:
* tokio-executor (0.1.3)
* tokio-io (0.1.8)
* tokio-reactor (0.1.4)
* tokio-threadpool (0.1.6)
* tokio-timer (0.2.6)
* tokio-udp (0.1.2)
