Internals have been shuffled around such that Request and Reponse are
now given only a mutable reference to the stream, instead of being
allowed to consume it. This allows the server to re-use the streams if
keep-alive is true.
A task pool is used, and the number of the threads can currently be
adjusted by using the `listen_threads()` method on Server.
[breaking-change]
Intertwining was a nice feature, but it slows down hyper significantly,
so it is being removed.
There is some fallout from this, mainly that Incoming has had its type
parameter changed to `<A = HttpAcceptor>` and Handler receiving one
bounded with `A: NetworkAcceptor`.
[breaking-change]
Fixes#112
A connection is returned from Incoming.next(), and can be passed to a
separate thread before any parsing happens. Call conn.open() to get a
Result<(Request, Response)>.
BREAKING CHANGE
Trying to default the type parameters leads to an ICE and strange type errors.
I think this is just due to the experimental state of default type params and
this change can be rolled back when they are fixed.
Expose Server::many for creating a Server that will listen on many (ip, port)
pairs.
Handler still receives a simple Iterator of (Request, Response) pairs.
This is a breaking change since it changes the representation of Listener,
but Handler and Server::http are unchanged in their API.
Fixes#7
The client benchmarks did not have to be changed at all for this whole
refactor, and the server benchmark only had to specify a single type parameter,
and only because it writes out the type of Listener, which is not normal
usage.
Server and client benchmarks show that this makes very little difference
in performance and using dynamic dispatch here is significantly more ergonomic.
This also bounds NetworkStream with Send to prevent incorrect implementations.
Allows the implementation of mock streams for testing and flexibility.
Fixes#5
This introduces a new Trait, NetworkStream, which abstracts over
the functionality provided by TcpStream so that it can be easily
mocked and extended in testing and hyper can be used for
other connection sources.
Introduces two Phantom Types, Fresh and Streaming, which indicate the status
of a Response.
Response::start translates an Response<Fresh> into a
Response<Streaming> by writing the StatusCode and Headers.
Response<Fresh> allows modification of Headers and StatusCode, but does
not allow writing to the body. Response<Streaming> has the opposite privileges.
This allows downstream users to have total control of their concurrency
strategy, while also exposing a very nice, streaming interface for frameworks
to build on.
This also resolves issues surrounding the use of IoResult as the return type
of Handler::handle, because handlers now have complete control over how to
handle internal failure.
