Struct futures_test::io::read::Limited

pub struct Limited<Io> { /* fields omitted */ }

I/O wrapper that limits the number of bytes written or read on each call.

See the limited and limited_write methods.

Implementations

impl<Io> Limited<Io>

pub fn get_ref(&self) -> &Io

Acquires a reference to the underlying I/O object that this adaptor is wrapping.

pub fn get_mut(&mut self) -> &mut Io

Acquires a mutable reference to the underlying I/O object that this adaptor is wrapping.

pub fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut Io>

Acquires a pinned mutable reference to the underlying I/O object that this adaptor is wrapping.

pub fn into_inner(self) -> Io

Consumes this adaptor returning the underlying I/O object.

Trait Implementations

impl<R: AsyncBufRead> AsyncBufRead for Limited<R>

pub 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.

pub 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<R: AsyncRead> AsyncRead for Limited<R>

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

Attempt to read from the AsyncRead into buf.

pub 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<W: AsyncWrite> AsyncWrite for Limited<W>

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

Attempt to write bytes from buf into the object.

pub 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.

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

Attempt to close the object.

pub 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<Io: Debug> Debug for Limited<Io>

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

Formats the value using the given formatter.

impl<'pin, Io> Unpin for Limited<Io> where
    __Limited<'pin, Io>: Unpin,
