Struct tokio::net::unix::OwnedWriteHalf

source ·
pub struct OwnedWriteHalf { /* private fields */ }
Expand description

Owned write half of a UnixStream, created by into_split.

Note that in the AsyncWrite implementation of this type, poll_shutdown will shut down the stream in the write direction. Dropping the write half will also shut down the write half of the stream.

Writing to an OwnedWriteHalf is usually done using the convenience methods found on the AsyncWriteExt trait.

Implementations§

source§

impl OwnedWriteHalf

source

pub fn reunite(self, other: OwnedReadHalf) -> Result<UnixStream, ReuniteError>

Attempts to put the two halves of a UnixStream back together and recover the original socket. Succeeds only if the two halves originated from the same call to into_split.

source

pub fn forget(self)

Destroys the write half, but don’t close the write half of the stream until the read half is dropped. If the read half has already been dropped, this closes the stream.

source

pub async fn ready(&self, interest: Interest) -> Result<Ready>

Waits for any of the requested ready states.

This function is usually paired with try_read() or try_write(). It can be used to concurrently read / write to the same socket on a single task without splitting the socket.

The function may complete without the socket being ready. This is a false-positive and attempting an operation will return with io::ErrorKind::WouldBlock. The function can also return with an empty Ready set, so you should always check the returned value and possibly wait again if the requested states are not set.

Cancel safety

This method is cancel safe. Once a readiness event occurs, the method will continue to return immediately until the readiness event is consumed by an attempt to read or write that fails with WouldBlock or Poll::Pending.

source

pub async fn writable(&self) -> Result<()>

Waits for the socket to become writable.

This function is equivalent to ready(Interest::WRITABLE) and is usually paired with try_write().

Cancel safety

This method is cancel safe. Once a readiness event occurs, the method will continue to return immediately until the readiness event is consumed by an attempt to write that fails with WouldBlock or Poll::Pending.

source

pub fn try_write(&self, buf: &[u8]) -> Result<usize>

Tries to write a buffer to the stream, returning how many bytes were written.

The function will attempt to write the entire contents of buf, but only part of the buffer may be written.

This function is usually paired with writable().

Return

If data is successfully written, Ok(n) is returned, where n is the number of bytes written. If the stream is not ready to write data, Err(io::ErrorKind::WouldBlock) is returned.

source

pub fn try_write_vectored(&self, buf: &[IoSlice<'_>]) -> Result<usize>

Tries to write several buffers to the stream, returning how many bytes were written.

Data is written from each buffer in order, with the final buffer read from possible being only partially consumed. This method behaves equivalently to a single call to try_write() with concatenated buffers.

This function is usually paired with writable().

Return

If data is successfully written, Ok(n) is returned, where n is the number of bytes written. If the stream is not ready to write data, Err(io::ErrorKind::WouldBlock) is returned.

source

pub fn peer_addr(&self) -> Result<SocketAddr>

Returns the socket address of the remote half of this connection.

source

pub fn local_addr(&self) -> Result<SocketAddr>

Returns the socket address of the local half of this connection.
