Struct AsyncReadWriteTake

pub struct AsyncReadWriteTake<RW: AsyncRead + AsyncWrite> { /* private fields */ }

Wraps a tokio::io::AsyncRead + tokio::io::AsyncWrite struct. Passes through reads and writes to the struct. Limits the number of bytes that can be read.

This is like tokio::io::Take that also passes through writes.

Implementations

impl<RW: AsyncRead + AsyncWrite + Unpin> AsyncReadWriteTake<RW>

pub fn new(read_writer: RW, len: u64) -> AsyncReadWriteTake<RW>

See AsyncReadWriteTake.

Trait Implementations

impl<RW: AsyncRead + AsyncWrite + Unpin> AsyncRead for AsyncReadWriteTake<RW>

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

Attempts to read from the AsyncRead into buf.

impl<RW: AsyncRead + AsyncWrite + Unpin> AsyncWrite for AsyncReadWriteTake<RW>

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 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.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.
