The client now has an option to allow parsing responses with obsolete line folding in headers. The option is off by default, since the spec recommends to reject such things if you can.
This value is like a high-water mark. It applies per stream. Once a
stream has buffered that amount of bytes to send, it won't poll more
data from the `HttpBody` until the stream has been able to flush under
it.
These options are currently available on the high-level builder only.
Along the way, rename the setters to follow the public API conventions
and add docs.
Closes#2461
When http2_only is true, we never try to open a new connection if there
is one open already, which means that if the existing connection that
gets checked out of the pool is closed, then the request won't happen.
Decouple preserving header case from FFI:
The feature is now supported in both the server and the client
and can be combined with the title case feature, for headers
which don't have entries in the header case map.
Closes#2313
* refactor: Use async/await in client.rs
* refactor: Simplify client.rs a bit more
* refactor: Allow !Unpin in Lazy
* Remove some impl Future
* Remove some combinator use
Make it possible to refer to Connected, Connection, HttpConnector, etc.
without enabling either of the http1/http2 features. This makes feature
selection work better for downstream libraries like hyper-openssl, which
don't want to commit to any particular protocol.
Fix#2376.
