| //! |
| //! There are two levels of APIs provided for construct HTTP clients: |
| //! |
| //! - The higher-level [`Client`](Client) type. |
| //! - The lower-level [`conn`](conn) module. |
| //! |
| //! # Client |
| //! |
| //! The [`Client`](Client) is the main way to send HTTP requests to a server. |
| //! The default `Client` provides these things on top of the lower-level API: |
| //! |
| //! - A default **connector**, able to resolve hostnames and connect to |
| //! destinations over plain-text TCP. |
| //! - A **pool** of existing connections, allowing better performance when |
| //! making multiple requests to the same hostname. |
| //! - Automatic setting of the `Host` header, based on the request `Uri`. |
| //! - Automatic request **retries** when a pooled connection is closed by the |
| //! server before any bytes have been written. |
| //! |
| //! Many of these features can configured, by making use of |
| //! [`Client::builder`](Client::builder). |
| //! |
| //! ## Example |
| //! |
| //! For a small example program simply fetching a URL, take a look at the |
| //! [full client example](https://github.com/hyperium/hyper/blob/master/examples/client.rs). |
| //! |
| //! ``` |
| //! # #[cfg(all(feature = "tcp", feature = "client", any(feature = "http1", feature = "http2")))] |
| //! # async fn fetch_httpbin() -> hyper::Result<()> { |
| //! use hyper::{body::HttpBody as _, Client, Uri}; |
| //! |
| //! let client = Client::new(); |
| //! |
| //! // Make a GET /ip to 'http://httpbin.org' |
| //! let res = client.get(Uri::from_static("http://httpbin.org/ip")).await?; |
| //! |
| //! // And then, if the request gets a response... |
| //! println!("status: {}", res.status()); |
| //! |
| //! // Concatenate the body stream into a single buffer... |
| //! let buf = hyper::body::to_bytes(res).await?; |
| //! |
| //! println!("body: {:?}", buf); |
| //! # Ok(()) |
| //! # } |
| //! # fn main () {} |
| //! ``` |
