Struct actix_web::body::SizedStream

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

Known sized streaming response wrapper.

This body implementation should be used if total size of stream is known. Data is sent as-is without using chunked transfer encoding.

Implementations

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

pub fn new(size: u64, stream: S) -> SizedStream<S>

Trait Implementations

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

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

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

Empty values are skipped to prevent SizedStream’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>

Try to convert into the complete chunk of body bytes.

fn boxed(self) -> BoxBody where
    Self: 'static, 

Converts this body into BoxBody.

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