source · [−]pub struct Body { /* private fields */ }
Available on crate feature
client
only.Expand description
A stream of Bytes
, used when receiving bodies.
A good default HttpBody

or body::aggregate
.
Implementations
sourceimpl Body
impl Body
sourcepub fn empty() -> 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());
sourcepub fn channel() -> (Sender, Body)
pub fn channel() -> (Sender, Body)
Create a Body
stream with an associated sender half.
Useful when wanting to stream chunks from another thread.
sourcepub fn wrap_stream<S, O, E>(stream: S) -> Bodywhere
S: 'static + Stream<Item = Result<O, E>> + Send,
O: 'static + Into<Bytes>,
E: 'static + Into<Box<dyn Error + Sync + Send + 'static, Global>>,
Available on crate feature stream
only.
pub fn wrap_stream<S, O, E>(stream: S) -> Bodywhere
S: 'static + Stream<Item = Result<O, E>> + Send,
O: 'static + Into<Bytes>,
E: 'static + Into<Box<dyn Error + Sync + Send + 'static, Global>>,
stream
only.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
.
