This patch updates the documentation for a number of APIs. It also
introduces a prelude module and an io facade module, re-exporting types
from tokio-io.
This patch is an intial implementation of the Tokio runtime. The Tokio
runtime provides an out of the box configuration for running I/O heavy
asynchronous applications.
As of now, the Tokio runtime is a combination of a work-stealing thread
pool as well as a background reactor to drive I/O resources.
This patch also includes tokio-executor, a hopefully short lived crate
that is based on the futures 0.2 executor RFC.
* Implement `Park` for `Reactor`
This enables the reactor to be used as the thread parker for executors.
This also adds an `Error` component to `Park`. With this change, a
`Reactor` and a `CurrentThread` can be combined to achieve the
capabilities of tokio-core.
This should allow configuration over what reactor accepted streams go on to by
giving back a libstd-bound object that can then be used later in conjunction
with `TcpStream::from_std`.
* Make Handle `Send + Sync`.
This is an initial implementation making `Handle: Send + Sync`. It uses
a `RwLock` to coordinate access to the underlying state storage. An
implementation without the lock is left to later.
This pass also leaves a lot of dead code that can be removed in later
commits.
* Remove reactor code related to message passing
The previous commit removed the need for using message passing to
communicate with the reactor. This commit removes all the unnecessary
code.
This patch disables various Unix-specific platform features that are
not enabled on Fuchsia. It also updates the mio version to 0.6.10,
which is the first release that supports Fuchsia.
Note that this brings in a lot of machinery just for the sake of
wrapping file descriptors as PollEvented. This should maybe be moved
into the public API of some crate.
