Struct RewindStream

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

Implementations

impl<S> RewindStream<S>

pub fn new(inner: S) -> Self

pub fn rewind(&mut self, data: &[u8])

pub fn into_inner(self) -> (S, Vec<u8>)

Trait Implementations

impl<S: AsyncRead + Unpin> AsyncRead for RewindStream<S>

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

Attempts to read from the AsyncRead into buf.

impl<S: AsyncWrite + Unpin> AsyncWrite for RewindStream<S>

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

Attempt to write bytes from buf into the object.

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

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

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

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

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

Like poll_write, except that it writes from a slice of buffers.

impl<S: Stream> Rewindable for RewindStream<S>

fn rewind(&mut self, bytes: &[u8]) -> Result<()>
