There are many changes involved with this, but let's just talk about
user-facing changes.
- Creating a `Client` and `Server` now needs a Tokio `Core` event loop
to attach to.
- `Request` and `Response` both no longer implement the
`std::io::{Read,Write}` traits, but instead represent their bodies as a
`futures::Stream` of items, where each item is a `Chunk`.
- The `Client.request` method now takes a `Request`, instead of being
used as a builder, and returns a `Future` that resolves to `Response`.
- The `Handler` trait for servers is no more, and instead the Tokio
`Service` trait is used. This allows interoperability with generic
middleware.
BREAKING CHANGE: A big sweeping set of breaking changes.
The old names followed the old style of including the module name and
"Error" in each variant. The new style is to refer to an error from its
owning module, and variants are now scoped to their enum, so there's no
need to include the enum name in the variant name.
BREAKING CHANGE: The terms `Http` and `Error` have been removed from the Error
type and its variants. `HttpError` should now be accessed as `hyper::Error`,
and variants like `HttpIoError` should be accessed as `Error::Io`.
httparse is a http1 stateless push parser. This not only speeds up
parsing right now with sync io, but will also be useful for when we get
async io, since it's push based instead of pull.
BREAKING CHANGE: Several public functions and types in the `http` module
have been removed. They have been replaced with 2 methods that handle
all of the http1 parsing.
This test case does not attempt to test all the methods exhaustively,
but it does at least test all the methods in the APIs. There's also a
check to make sure that Method can be used as part of a hash-table key.
