* Denied all warnings in tests, and denied rust_2018_idioms violations
* Bumped the crate version and set publish = false
* Pruned dependencies:
- Only pull in tokio-sync on windows where it is used
- Removed unused dev-dependencies
* Switch to Async{Read, Write} traits from tokio-io rather than
futures-io
* Use #[tokio::test] where possible
* Removed deprecated items
* Fix all doc examples
* TryFrom<net::TcpListener> for TcpListener
* TryFrom<net::TcpStream> for TcpStream
* TryFrom<net::UdpSocket> for UdpSocket
* TryFrom<net::UnixDatagram> for UnixDatagram
* TryFrom<net::UnixListener> for UnixListener
* TryFrom<net::UnixStream> for UnixStream
* TryFrom<UnixDatagram> for mio_uds::UnixDatagram
* TryFrom<File> for io::File
* From<io::File> for File
* This simplifies the API surface by returning () instead of the signal
number that was used during registration. This also more closely mirrors
the cross-platform `CtrlC` event stream API
* This is a **breaking change**
* Add a new `windows::CtrlBreak` struct which wil represent a stream of
CTRL_BREAK_EVENT signals on Windows systems
* The `windows::Event` type is no longer publicly accessible and is
replaced by using `CtrlC` or `windows::CtrlBreak`.
[breaking-change]
Removes the `Send` requirement to futures passed to `Runtime::block_on`.
Previously, `block_on` was implemented by sending the future to a
runtime thread. In order to do this, the future must be Send.
The reason why the future is sent to the pool is because we cannot
guarantee, while off the pool, that a reactor / timer thread is running.
This is due to a limitation in the current version of tokio-threadpool.
There is a plan to fix this (#1177), but the proper fix is non trivial.
In order to unblock APIs that require this, this patch updates the
runtime to spawn an always running thread containing a reactor and
timer. All calls to `block_on` will use that reactor and timer.
We want executors to enforce that there are never multiple active at the
same time. This is ensured through `Enter`, which will panic if you
attempt to create more than one. However, by requiring you to pass an
`&mut Enter` to `executor::with_default`, we were *also* disallowing
temporarily overriding the current executor.
This patch removes that requirement.
