Struct actix_http::body::SizedStream

source · [−]

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

Expand description

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

source

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

source

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

Trait Implementations

source

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

source

fn poll_next(
self: Pin<&mut Self>,
cx: &mut Context<'_>
) -> Poll<Option<Result<Bytes, Self::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. Read more

source

fn size(&self) -> BodySize

Body size hint. Read more

source

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

source

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

Converts this body into BoxBody.
