Generally speaking, it is unsafe to access to perform asynchronous
operations using `&self`. Taking `&self` allows usage from a `Sync`
context, which has unexpected results.
Taking `&mut self` to perform these operations prevents using these
asynchronous values from across tasks (unless they are wrapped in
`RefCell` or `Mutex`.
* Refactor UDP SendDgram & RecvDgram
Get rid of unnamed structs in the favor of private structs with named fields
* Change the signature of UdpCodec::encode
Now it is:
```
fn encode(&mut self, msg: Self::Out, buf: &mut Vec<u8>) -> Result<SocketAddr, Self::Error>;
```

* Fix compilation error from `mio` crate
This commit removes the `Handle` argument from the following constructors
* `TcpListener::bind`
* `TcpStream::connect`
* `UdpSocket::bind`
The `Handle` argument remains on the various `*_std` constructors as they're
more low-level, but this otherwise is intended to set forth a precedent of by
default not taking `Handle` arguments and instead relying on the global
`Handle::default` return value when necesary.
This commit is targeted at solving tokio-rs/tokio-core#12 and incorporates the
solution from tokio-rs/tokio-core#17. Namely the `need_read` and `need_write`
functions on `PollEvented` now return an error when the connected reactor has
gone away and the task cannot be blocked. This will typically naturally
translate to errors being returned by various connected I/O objects and should
help tear down the world in a clean-ish fashion.
This commit renames the various constructors of networking types to have a
`_std` suffix instead of a smorgasboard of other suffixes, canonicalizing on
`_std` as the suffix for constructors which take the libstd corresponding types.
* small doc cleanups in PollEvented
* small doc cleanups in IoToken
* improve crate level documentation
- Add links to the futures, mio and tokio-uds crates.
- Add links to various structs and types mentioned.
- use eprintln for error reporting in the example.
* improvements to the UdpSocket documentation
- Fixed links usage.
- Removed references to a no longer existing `Window` struct.
- Made notes about using functions in context of a future.
* documentation improvements to UdpFramed and UdpCodec
- Since HTTP uses TCP (QUIC aside) using it as an example in an UDP
protocol feels wrong.
- Make the note of tampering with the underlying streams more explicit.
* update reactor module level documentation
Adds an explanation of every public struct.
* expand Handle and Remote documentation
* expand net module documentation
Adds an explanation of every public struct and how they work together.
* update TcpListener documentation
Reorder the various option methods; get first then set.
Note about panicing added to poll_read.
* remove mention of none-existing future R
* improve documentation of TcpStream
* fix UdpSocket doc
This when wrong when merging various commits.
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.
* Move to `std::net` as it's all purely UDP related
* Rename to `UdpCodec` and `UdpFramed` to give a consistent `Udp` prefix
* Add `RecvDgram`, rename `SendDGram` to `SendDgram`
* Touch up some style here and there
