Struct hyper::Body [] [src]

#[must_use = "streams do nothing unless polled"]
pub struct Body { /* fields omitted */ }

A stream of Chunks, used when receiving bodies.

A good default Payload to use in many applications.

Also implements futures::Stream, so stream combinators may be used.

Methods

impl Body
[src]

[src]

Create an empty Body stream.

Example

use hyper::{Body, Request};

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

[src]

Create a Body stream with an associated sender half.

Useful when wanting to stream chunks from another thread.

[src]

Wrap a futures Stream in a box inside Body.

Example

let chunks = vec![
    "hello",
    " ",
    "world",
];

let stream = futures::stream::iter_ok::<_, ::std::io::Error>(chunks);

let body = Body::wrap_stream(stream);
