Tokio's `AsyncWrite` trait once again has support for vectored writes in Tokio 0.3.4 (see tokio-rs/tokio#3149). This branch re-enables vectored writes in Hyper for HTTP/1. Using vectored writes in HTTP/2 will require an upstream change in the `h2` crate as well. I've removed the adaptive write buffer implementation that attempts to detect whether vectored IO is or is not available, since the Tokio 0.3.4 `AsyncWrite` trait exposes this directly via the `is_write_vectored` method. Now, we just ask the IO whether or not it supports vectored writes, and configure the buffer accordingly. This makes the implementation somewhat simpler. This also removes `http1_writev()` methods from the builders. These are no longer necessary, as Hyper can now determine whether or not to use vectored writes based on `is_write_vectored`, rather than trying to auto-detect it. Closes #2320 BREAKING CHANGE: Removed `http1_writev` methods from `client::Builder`, `client::conn::Builder`, `server::Builder`, and `server::conn::Builder`. Vectored writes are now enabled based on whether the `AsyncWrite` implementation in use supports them, rather than though adaptive detection. To explicitly disable vectored writes, users may wrap the IO in a newtype that implements `AsyncRead` and `AsyncWrite` and returns `false` from its `AsyncWrite::is_write_vectored` method.

"Low-level"
hyper is a relatively low-level library, meant to be a building block for libraries and applications.
If you are looking for a convenient HTTP client, then you may wish to consider reqwest. If you are looking for a convenient HTTP server, then you may wish to consider warp. Both are built on top of this library.
