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 fixes an unsafe transmute that could cause use-after-frees
on collision resolution in the headers hash and avoids allocating
for cases where it is not necessary.
Fixes#12
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.
