Implementations§

impl Body

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

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

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

Create a new Body with a maximum size limit.

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 + Sync + Send>>,

Create a new Body from a Stream.

pub fn limited(self, limit: usize) -> Body

Create a new Body from a Stream with a maximum size limit.

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.

pub fn into_event_stream<T>(self) -> EventStream<BodyDataStream, T>
where T: EventDataRead,

Convert the body into a Stream of sse::Events.

https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events.

pub fn into_string_data_event_stream(self) -> EventStream<BodyDataStream>

Convert the body into a Stream of sse::Events with optional string data.

https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events.

pub async fn chunk( &mut self, ) -> Result<Option<Bytes>, Box<dyn Error + Sync + Send>>

Stream a chunk of the response body.

When the response body has been exhausted, this will return None.
