Struct ajars_actix_web::actix_web::dev::SizedStream [−]
pub struct SizedStream<S> { /* fields omitted */ }
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
pub fn new(size: u64, stream: S) -> SizedStream<S>
Trait Implementations
pub fn from(s: SizedStream<S>) -> AnyBody
pub fn from(s: SizedStream<S>) -> AnyBody
Performs the conversion.

E: Into<Box<dyn Error + 'static, Global>> + 'static,
S: Stream<Item = Result<Bytes, E>>,
impl<S, E> MessageBody for SizedStream<S> where
E: Into<Box<dyn Error + 'static, Global>> + 'static,
S: Stream<Item = Result<Bytes, E>>,
pub fn poll_next(
self: Pin<&mut SizedStream<S>>,
cx: &mut Context<'_>
) -> Poll<Option<Result<Bytes, <SizedStream<S> as MessageBody>::Error>>>
pub 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.
