pub struct Body { /* private fields */ }
Expand description

A stream of Bytes, used when receiving bodies.

A good default HttpBody to use in many applications.

Note: To read the full body, use body::to_bytes or body::aggregate.

Implementations

Create an empty Body stream.

Example
use hyper::{Body, Request};

// create a `GET /` request
let get = Request::new(Body::empty());

Create a Body stream with an associated sender half.

Useful when wanting to stream chunks from another thread.

Wrap a futures Stream in a box inside Body.

Example
let chunks: Vec<Result<_, std::io::Error>> = vec![
    Ok("hello"),
    Ok(" "),
    Ok("world"),
];

let stream = futures_util::stream::iter(chunks);

let body = Body::wrap_stream(stream);
Optional

This function requires enabling the stream feature in your Cargo.toml.
