Struct fixed_buffer_tokio::AsyncReadWriteTake

pub struct AsyncReadWriteTake<'a, RW: AsyncRead + AsyncWrite + Send + Unpin> { /* fields omitted */ }

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

This is like tokio::io::Take that passes through writes. This makes it usable with AsyncRead+AsyncWrite objects like tokio::net::TcpStream and tokio_rustls::server::TlsStream.

Implementations

impl<'a, RW: AsyncRead + AsyncWrite + Send + Unpin> AsyncReadWriteTake<'a, RW>

pub fn new(read_writer: &'a mut RW, len: u64) -> AsyncReadWriteTake<'a, RW>

See AsyncReadWriteTake.

Trait Implementations

impl<'a, RW: AsyncRead + AsyncWrite + Send + Unpin> AsyncRead for AsyncReadWriteTake<'a, RW>

pub 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<'a, RW: AsyncRead + AsyncWrite + Send + Unpin> AsyncWrite for AsyncReadWriteTake<'a, RW>

pub 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.

pub 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.

pub 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.

pub 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.

pub fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.
