Struct hyper::common::io::rewind::Rewind

pub(crate) struct Rewind<T> {
    pre: Option<Bytes>,
    inner: T,
}

Combine a buffer with an IO, rewinding reads to use the buffer.

Fields

pre: Option<Bytes>

inner: T

Implementations

impl<T> Rewind<T>

pub(crate) fn new(io: T) -> Self

pub(crate) fn new_buffered(io: T, buf: Bytes) -> Self

pub(crate) fn rewind(&mut self, bs: Bytes)

pub(crate) fn into_inner(self) -> (T, Bytes)

Trait Implementations

impl<T> AsyncRead for Rewind<T>

where T: AsyncRead + Unpin,

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

Attempts to read from the AsyncRead into buf.

impl<T> AsyncWrite for Rewind<T>

where T: AsyncWrite + Unpin,

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>>

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

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

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<()>>

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.

impl<T: Debug> Debug for Rewind<T>

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

Formats the value using the given formatter.
