Struct actix_web::body::BodyStream

pub struct BodyStream<S> { /* private fields */ }

Streaming response wrapper.

Response does not contain Content-Length header and appropriate transfer encoding is used.

Implementations

impl<S, E> BodyStream<S>where
    S: Stream<Item = Result<Bytes, E>>,
    E: Into<Box<dyn Error + 'static, Global>> + 'static,

pub fn new(stream: S) -> BodyStream<S>

Trait Implementations

impl<S, E> MessageBody for BodyStream<S>where
    S: Stream<Item = Result<Bytes, E>>,
    E: Into<Box<dyn Error + 'static, Global>> + 'static,

fn poll_next(
    self: Pin<&mut BodyStream<S>>,
    cx: &mut Context<'_>
) -> Poll<Option<Result<Bytes, <BodyStream<S> as MessageBody>::Error>>>

Attempts to pull out the next value of the underlying Stream.

Empty values are skipped to prevent BodyStream’s transmission being ended on a zero-length chunk, but rather proceed until the underlying Stream ends.

type Error = E

The type of error that will be returned if streaming body fails.

fn size(&self) -> BodySize

Body size hint.

fn try_into_bytes(self) -> Result<Bytes, Self>where
    Self: Sized,

Try to convert into the complete chunk of body bytes.

fn boxed(self) -> BoxBodywhere
    Self: Sized + 'static,

Wraps this body into a BoxBody.

impl<'__pin, S> Unpin for BodyStream<S>where
    __Origin<'__pin, S>: Unpin,
