This commit extracts the concrete implementation of `FrameIo` in tokio-proto to
tokio-core under the name `EasyFramed`. This extraction is accompanied with a
new `EasyBuf` buffer type to work with when parsing types.
The purpose of this movement is to provide a clear and easy entry point at the
`FramedIo` layer for those who need it. Eventually these buffer types will get
replaced or moved to the `bytes` crate, but in the interest of an 0.1 release
and remaining backwards compatible with the tokio-core 0.1 release this is
adding a separate module.
The other read futures (read_exact, read_until, etc.) all expose their
concrete future types so that function signatures can return them, but
until now `read()` didn't. Exposing it with the name "Read" causes
naming conflicts with the std::io::Read trait, so the easiest thing to
do is to just change the name. Importing std::io::Read under a different
name would've been an option too, but that would probably be annoying
for consumers in the same way it's annoying for us.
The original PR (https://github.com/tokio-rs/tokio-core/pull/29) decided
that "read" was a better name than "read_some", so I'm leaving the top
level functions unchanged. I don't have a strong opinion about it one
way or the other, but I *do* think it's worth bikeshedding a little bit.
Python's asyncio library actually ended up with a very similar issue
around naming inconsistency between the sync and async worlds, and we
can hopefully avoid repeating that: https://bugs.python.org/issue22279
In general it's easier to implement and should have more predictable performance
semantics for applications in general. More serious timer usage can go through
`tokio-timer` which has properly configurable timer wheels and such.
Closes#2Closes#7
* Handle -> Remote
* Pinned -> Handle
All APIs now take a `&Handle` by default and in general can return an immediate
`io::Result` instead of an `IoFuture`. This reflects how most usage will likely
be done through handles rather than remotes, and also all previous functionality
can be recovered with a `oneshot` plus `Remote::spawn`.
Closes#15
* Remove `LoopData` as it's no longer necessary
* Add `LoopHandle::spawn` to spawn new futures onto an event loop
* Add `LoopData::spawn` to also spawn new futures onto an event loop
* Rejigger the implementation of the event loop a bit (make a slab of futures),
but otherwise everything else is pretty constant.
