Struct Body

source
pub struct Body(/* private fields */);
Expand description

The body type used in axum requests and responses.

Implementations§

source§

impl Body

source

pub fn new<B>(body: B) -> Self
where B: Body<Data = Bytes> + Send + 'static, B::Error: Into<BoxError>,

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

source

pub fn empty() -> Self

Create an empty body.

source

pub fn from_stream<S>(stream: S) -> Self
where S: TryStream + Send + 'static, S::Ok: Into<Bytes>, S::Error: Into<BoxError>,

Create a new Body from a Stream.

source

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§

impl IntoResponse for Body

source§

fn into_response(self) -> Response

Create a response.
