It is not possible to connect to an IPv4 address from an IPv6 address or
vice-versa so don't waste time trying. If no remote addresses match then a
"missing connect error" will now occur.
Closes#1903
BREAKING CHANGE: The `Resolve` trait is gone. All custom resolves should
implement `tower::Service` instead.
The error type of `HttpConnector` has been changed away from
`std::io::Error`.
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 takes the same strategy as golang, where the timeout value is
divided equally between the candidate socket addresses.
If happy eyeballs is enabled, the division takes place "below" the
IPv4/IPv6 partitioning.
The `HttpConnector` and `AddrListener` types which make use of
`tokio::tcp` have been made their own optional feature. This allows
using them without requiring the *full* tokio runtime.
- Placed all cases of "unexpected bytes" errors into the
`UnexpectedMessage` variant.
- Placed all cases of "unexpected EOF" errors into the
`IncompleteMessage` variant. Description is now generic about
"connection closed before message completed", instead of mentioning
"request" or "response.
- Added `Error::is_incomplete_message()` accessor to help checking for
unexpected closures.
- Renamed some variants to be clearer when viewing the `Debug` format.
- Collected all "user" errors into an internal `User` enum, to prevent
forgetting to update the `is_user()` method.
* Add `server::conn::Connection::without_shutdown`
Returns wrapper Future instance which allows
to use `poll_without_shutdown` method
more ergonomically.
* Add `client::conn::Connection::without_shutdown`
Returns wrapper Future instance which allows
to use `poll_without_shutdown` method
more ergonomically.
* Improve `poll_without_shutdown` docs
Closes#1786
