Struct Body

pub struct Body(/* private fields */);

Expand description

The body type used in axum requests and responses.

Implementations§

impl Body

pub fn new<B>(body: B) -> Body
where B: Body<Data = Bytes> + Send + 'static, <B as Body>::Error: Into<Box<dyn Error + Send + Sync>>,

Create a new Body that wraps another http_body::Body.

pub fn empty() -> Body

Create an empty body.

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

Create a new Body from a Stream.

pub fn into_data_stream(self) -> BodyDataStream

Convert the body into a Stream of data frames.

Non-data frames (such as trailers) will be discarded. Use http_body_util::BodyStream if you need a Stream of all frame types.

Trait Implementations§

type Data = Bytes

Values yielded by the Body.

type Error = Error

The error type this Body might generate.

fn poll_frame( self: Pin<&mut Body>, cx: &mut Context<'_>, ) -> Poll<Option<Result<Frame<<Body as Body>::Data>, <Body as Body>::Error>>>

Attempt to pull out the next data buffer of this stream.
