The default Body type is used in the client in a Pool, so it has to be
Send. On the server, we can use a !Send type if the executor is single
threaded.
Expand the existing example to show that.
This branch updates `bytes` and `http-body` to the latest versions. The
`http-body` version that uses `bytes` 0.6 hasn't been released yet, so
we depend on it via a git dep for now. Presumably Hyper and `http-body`
will synchronize their releases.
Other than that, this is a pretty mechanical update. Should fix the
build and unblock the `h2` update to use vectored writes.
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
When the body type of a `Request` or `Response` implements `HttpBody`,
the `Request` or `Response` itself now implements `HttpBody`.
This allows writing things like `hyper::body::aggregate(req)` instead of
`hyper::body::aggregate(req.into_body())`.
Closes#2067
Adds utility functions to `hyper::body` to help asynchronously
collecting all the buffers of some `HttpBody` into one.
- `aggregate` will collect all into an `impl Buf` without copying the
contents. This is ideal if you don't need a contiguous buffer.
- `to_bytes` will copy all the data into a single contiguous `Bytes`
buffer.
Instead of returning a tuple `(impl AsyncRead + AsyncWrite, Connected)`,
this adds a new trait, `hyper::client::connect::Connection`, which
allows querying the connection type for a `Connected`.
BREAKING CHANGE: Connectors no longer return a tuple of
`(T, Connected)`, but a single `T: Connection`.
The `hyper::rt::Executor` trait allows defining custom executors to be
used with hyper's `Client` and `Server`.
Closes#1944
BREAKING CHANGE: Any type passed to the `executor` builder methods must
now implement `hyper::rt::Executor`.
`hyper::rt::spawn` usage should be replaced with `tokio::task::spawn`.
`hyper::rt::run` usage should be replaced with `#[tokio::main]` or
managing a `tokio::runtime::Runtime` manually.
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
