cc #2223
BREAKING CHANGE: The HTTP client of hyper is now an optional feature. To
enable the client, add `features = ["client"]` to the dependency in
your `Cargo.toml`.
cc #2251
BREAKING CHANGE: This puts all HTTP/1 methods and support behind an
`http1` cargo feature, which will not be enabled by default. To use
HTTP/1, add `features = ["http1"]` to the hyper dependency in your
`Cargo.toml`.
Add `examples/service_struct_impl.rs`, which provides an up-to-date
example of implementing MakeService and Service on custom types.
The `Svc` struct has a Counter, which demonstrates how to instantiate
shared resources in the `MakeSvc` and pass the resource to the
services. Updates the `examples/README.md` and the doc in
`src/service/mod.rs`.
Closes#1691
The `Connect` trait is now essentially an alias for
`Service<Destination>`, with a blanket implementation as such, and is
sealed.
Closes#1902
BREAKING CHANGE: Any manual implementations of `Connect` must instead
implement `tower::Service<Destination>`.
The only important trait for a user is the `tower::Service` trait, which
is now available also at `hyper::service::Service`. The other "trait
aliases" are no longer publicly exported, as people thought they had to
implement them.
Also removes dependency on `tower-make`, which is trivial but otherwise
shouldn't affect anyone.
Closes#1959
This adjusts the way `Service`s are created for a `hyper::Server`. The
`MakeService` trait allows receiving an argument when creating a
`Service`. The implementation for `hyper::Server` expects to pass a
reference to the accepted transport (so, `&Incoming::Item`). The user
can inspect the transport before making a `Service`.
In practice, this allows for things like getting the remote socket
address, or the TLS certification, or similar.
To prevent a breaking change, there is a blanket implementation of
`MakeService` for any `NewService`. Besides implementing `MakeService`
directly, there is also added `hyper::service::make_service_fn`.
Closes#1650
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.
