//! HTTP Client //! //! 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). //! //! ``` //! use hyper::{body::HttpBody as _, Client, Uri}; //! //! # #[cfg(feature = "tcp")] //! # async fn fetch_httpbin() -> hyper::Result<()> { //! 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 () {} //! ``` #[cfg(feature = "tcp")] pub use self::connect::HttpConnector; pub mod connect; #[cfg(all(test, feature = "runtime"))] mod tests; cfg_feature! { #![any(feature = "http1", feature = "http2")] pub use self::client::{Builder, Client, ResponseFuture}; mod client; pub mod conn; pub(super) mod dispatch; mod pool; pub mod service; }
