Struct hyper::body::Body [−][src]
A stream of Bytes
, used when receiving bodies.
A good default HttpBody
to use in many
applications.
Implementations
impl Body
[src]
pub fn empty() -> Body
[src]
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)
[src]
Create a Body
stream with an associated sender half.
Useful when wanting to stream chunks from another thread.
pub fn wrap_stream<S, O, E>(stream: S) -> Body where
S: Stream<Item = Result<O, E>> + Send + 'static,
O: Into<Bytes> + 'static,
E: Into<Box<dyn StdError + Send + Sync>> + 'static,
[src]
S: Stream<Item = Result<O, E>> + Send + 'static,
O: Into<Bytes> + 'static,
E: Into<Box<dyn StdError + Send + Sync>> + 'static,
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
.
pub fn on_upgrade(self) -> OnUpgradeⓘ
[src]
Converts this Body
into a Future
of a pending HTTP upgrade.
See the upgrade
module for more.
Trait Implementations
impl Body for Body
[src]
type Data = Bytes
Values yielded by the Body
.

might generate.
