-//! ## Code example structure
-//! Note that all the following examples expect to be run outside of `main` because `?` is used. Like so:
-//!
-//! ```rust
-//! use reqwest::{Error, Response};
-//!
-//! fn run() -> Result<(), Error> {
-//!     let body = reqwest::get("https://www.rust-lang.org")?
-//!         .text()?;
-//!
-//!     println!("body = {:?}", body);
-//!     Ok(())
-//! }
-//!
-//! fn main() {
-//!     run();
-//! }
-//! ```
-//!
 //! ## Making a GET request
 //!
 //! For a single request, you can use the [`get`][get] shortcut method.
