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

An asynchronous request body.

Implementations§

source§

impl Body

source

pub fn as_bytes(&self) -> Option<&[u8]>

Returns a reference to the internal data of the Body.

None is returned, if the underlying data is a stream.

source

pub fn wrap_stream<S>(stream: S) -> Body
where S: TryStream + Send + 'static, S::Error: Into<Box<dyn Error + Send + Sync>>, Bytes: From<S::Ok>,

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 requires the stream feature to be enabled.

source

pub fn wrap<B>(inner: B) -> Body
where B: HttpBody + Send + Sync + 'static, B::Data: Into<Bytes>, B::Error: Into<Box<dyn Error + Send + Sync>>,

Wrap a HttpBody in a box inside Body.

§Example
let content = "hello,world!".to_string();

let body = Body::wrap(content);
