Struct Body

pub struct Body { /* private fields */ }

Expand description

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.

Implementations§

impl Body

pub fn empty() -> Body

Create an empty Body stream.

§Example

use hyper::{Body, Request};

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

pub fn channel() -> (Sender, Body)

Create a Body stream with an associated sender half.

Useful when wanting to stream chunks from another thread.

pub fn wrap_stream<S>(stream: S) -> Body
where S: Stream + Send + 'static, <S as Stream>::Error: Into<Box<dyn Error + Sync + Send>>, Chunk: From<<S as Stream>::Item>,

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);

pub fn on_upgrade(self) -> OnUpgrade

Converts this Body into a Future of a pending HTTP upgrade.

See the upgrade module for more.
