I'd probably do

use futures::{Future, Stream}; // 0.1.25
use hyper; // 0.12.14 
use std::str;

type Error = Box<dyn std::error::Error>;

fn example(body: hyper::Body) -> impl Future<Item = String, Error = Error> {
    body.map_err(Error::from)
        .concat2()
        .and_then(|c| {
            str::from_utf8(&c).map(str::to_owned).map_err(Error::from)
        })
}
