Struct futures_util::stream::IntoAsyncRead

#[must_use = "readers do nothing unless polled"]
pub struct IntoAsyncRead<St> where
    St: TryStream<Error = Error> + Unpin,
    St::Ok: AsRef<[u8]>,  { /* fields omitted */ }

This is supported on crate feature io only.

Reader for the into_async_read method.

Trait Implementations

impl<St> AsyncBufRead for IntoAsyncRead<St> where
    St: TryStream<Error = Error> + Unpin,
    St::Ok: AsRef<[u8]>, 

fn poll_fill_buf(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<&[u8]>>

Attempt to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(self: Pin<&mut Self>, amount: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to poll_read.

impl<St> AsyncRead for IntoAsyncRead<St> where
    St: TryStream<Error = Error> + Unpin,
    St::Ok: AsRef<[u8]>, 

fn poll_read(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &mut [u8]
) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into buf.

unsafe fn initializer(&self) -> Initializer

Determines if this AsyncReader can work with buffers of uninitialized memory.

fn poll_read_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    bufs: &mut [IoSliceMut<'_>]
) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl<St> AsyncWrite for IntoAsyncRead<St> where
    St: TryStream<Error = Error> + AsyncWrite + Unpin,
    St::Ok: AsRef<[u8]>, 

fn poll_write(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &[u8]
) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to close the object.

fn poll_write_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    bufs: &[IoSlice<'_>]
) -> Poll<Result<usize, Error>>

Attempt to write bytes from bufs into the object using vectored IO operations.

impl<St: Debug> Debug for IntoAsyncRead<St> where
    St: TryStream<Error = Error> + Unpin,
    St::Ok: AsRef<[u8]>,
    St::Ok: Debug, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<St> Unpin for IntoAsyncRead<St> where
    St: TryStream<Error = Error> + Unpin,
    St::Ok: AsRef<[u8]>,
