This removes the `tcp` feature from hyper's `Cargo.toml`, and the code it enabled:
- `HttpConnector`
- `GaiResolver`
- `AddrStream`
And parts of `Client` and `Server` that used those types. Alternatives will be available in the `hyper-util` crate.
Closes#2856

This introduces the `hyper::service` module, which replaces
`tokio-service`.
Since the trait is specific to hyper, its associated
types have been adjusted. It didn't make sense to need to define
`Service<Request=http::Request>`, since we already know the context is
HTTP. Instead, the request and response bodies are associated types now,
and slightly stricter bounds have been placed on `Error`.
The helpers `service_fn` and `service_fn_ok` should be sufficient for
now to ease creating `Service`s.
The `NewService` trait now allows service creation to also be
asynchronous.
These traits are similar to `tower` in nature, and possibly will be
replaced completely by it in the future. For now, hyper defining its own
allows the traits to have better context, and prevents breaking changes
in `tower` from affecting hyper.
Closes#1461
BREAKING CHANGE: The `Service` trait has changed: it has some changed
associated types, and `call` is now bound to `&mut self`.
The `NewService` trait has changed: it has some changed associated
types, and `new_service` now returns a `Future`.
`Client` no longer implements `Service` for now.
`hyper::server::conn::Serve` now returns `Connecting` instead of
`Connection`s, since `new_service` can now return a `Future`. The
`Connecting` is a future wrapping the new service future, returning
a `Connection` afterwards. In many cases, `Future::flatten` can be
used.
The `hyper::Server` is now a proper higher-level API for running HTTP
servers. There is a related `hyper::server::Builder` type, to construct
a `Server`. All other types (`Http`, `Serve`, etc) were moved into the
"lower-level" `hyper::server::conn` module.
The `Server` is a `Future` representing a listening HTTP server. Options
needed to build one are set on the `Builder`.
As `Server` is just a `Future`, it no longer owns a thread-blocking
executor, and can thus be run next to other servers, clients, or
what-have-you.
Closes#1322Closes#1263
BREAKING CHANGE: The `Server` is no longer created from `Http::bind`,
nor is it `run`. It is a `Future` that must be polled by an
`Executor`.
The `hyper::server::Http` type has move to
`hyper::server::conn::Http`.
**The `Error` is now an opaque struct**, which allows for more variants to
be added freely, and the internal representation to change without being
breaking changes.
For inspecting an `Error`, there are several `is_*` methods to check for
certain classes of errors, such as `Error::is_parse()`. The `cause` can
also be inspected, like before. This likely seems like a downgrade, but
more inspection can be added as needed!
The `Error` now knows about more states, which gives much more context
around when a certain error occurs. This is also expressed in the
description and `fmt` messages.
**Most places where a user would provide an error to hyper can now pass
any error type** (`E: Into<Box<std::error::Error>>`). This error is passed
back in relevant places, and can be useful for logging. This should make
it much clearer about what error a user should provide to hyper: any it
feels is relevant!
Closes#1128Closes#1130Closes#1431Closes#1338
BREAKING CHANGE: `Error` is no longer an enum to pattern match over, or
to construct. Code will need to be updated accordingly.
For body streams or `Service`s, inference might be unable to determine
what error type you mean to return. Starting in Rust 1.26, you could
just label that as `!` if you never return an error.
BREAKING CHANGE: `Method`, `Request`, `Response`, `StatusCode`,
`Version`, and `Uri` have been replaced with types from the `http`
crate. The `hyper::header` module is gone for now.
Removed `Client::get`, since it needed to construct a `Request<B>`
with an empty body. Just use `Client::request` instead.
Removed `compat` cargo feature, and `compat` related API.
All instances of `old_io` and `old_path` were switched to use the new
shiny `std::io`, `std::net`, and `std::path` modules. This means that
`Request` and `Response` implement `Read` and `Write` now.
Because of the changes to `TcpListener`, this also takes the opportunity
to correct the method usage of `Server`. As with other
languages/frameworks, the server is first created with a handler, and
then a host/port is passed to a `listen` method. This reverses what
`Server` used to do.
Closes#347
BREAKING CHANGE: Check the docs. Everything was touched.
- Includes ergonomic traits like IntoUrl and IntoBody, allowing easy
usage.
- Client can have a RedirectPolicy.
- Client can have a SslVerifier.
Updated benchmarks for client. (Disabled rust-http client bench since it
hangs.)
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
Latest 0.13.0-nightly gives this:
warning: static constant `phrase` should have an uppercase name such as
`PHRASE`, #[warn(non_upper_case_globals)] on by default
The client Request now uses the same system as a server Response to track
the write status of headers, and the API has been updated accordingly.
Additionally, the Request constructors have been moved onto the Request object
instead of being top-level hyper functions, as this better namespaces the
client and Server.
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.
Adds a benchmark for testing the speed of hyper's server.
Due to limitations of rust-http, `cargo bench` now needs to be
killed after running because there is no way to kill a rust-http
server after you start it.
