Struct BufStream 

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

A stream with a read buffer and a write buffer in front: a BufReader around a BufWriter.

Implementations

impl<S> BufStream<S>

pub fn new(stream: S) -> Self

Buffers of 8 KiB each way in front of stream.

pub fn with_capacity(read: usize, write: usize, stream: S) -> Self

A read buffer of read bytes and a write buffer of write bytes in front of stream.

pub fn get_ref(&self) -> &S

The stream inside.

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

The stream inside, to change.

pub fn into_inner(self) -> S

The stream inside, taken back; the bytes buffered either way are lost.

Trait Implementations

impl<S: AsyncRead + AsyncWrite + Unpin> AsyncBufRead for BufStream<S>

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<S: AsyncRead + AsyncWrite + Unpin> AsyncRead for BufStream<S>

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

Attempt to read from the AsyncRead into buf.

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<S: AsyncRead + AsyncWrite + Unpin> AsyncWrite for BufStream<S>

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

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

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.

impl<S: Debug> Debug for BufStream<S>

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

Formats the value using the given formatter.
