Struct tokio::net::UnixStream

pub struct UnixStream { /* fields omitted */ }

A structure representing a connected Unix socket.

This socket can be connected directly with UnixStream::connect or accepted from a listener with UnixListener::incoming. Additionally, a pair of anonymous Unix sockets can be created with UnixStream::pair.

Methods

impl UnixStream

pub async fn connect<P>(path: P) -> Result<UnixStream> where
    P: AsRef<Path>, 

Connects to the socket named by path.

This function will create a new Unix socket and connect to the path specified, associating the returned stream with the default event loop's handle.

pub fn from_std(stream: UnixStream) -> Result<UnixStream>

Consumes a UnixStream in the standard library and returns a nonblocking UnixStream from this crate.

The returned stream will be associated with the given event loop specified by handle and is ready to perform I/O.

Panics

This function panics if thread-local runtime is not set.

The runtime is usually set implicitly when this function is called from a future driven by a tokio runtime, otherwise runtime can be set explicitly with Handle::enter function.

pub fn pair() -> Result<(UnixStream, UnixStream)>

Creates an unnamed pair of connected sockets.

This function will create a pair of interconnected Unix sockets for communicating back and forth between one another. Each socket will be associated with the default event loop's handle.

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

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

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

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

pub fn peer_cred(&self) -> Result<UCred>

Returns effective credentials of the process which called connect or pair.

pub fn take_error(&self) -> Result<Option<Error>>

Returns the value of the SO_ERROR option.

pub fn shutdown(&self, how: Shutdown) -> Result<()>

Shuts down the read, write, or both halves of this connection.

This function will cause all pending and future I/O calls on the specified portions to immediately return with an appropriate value (see the documentation of Shutdown).

pub fn split(&mut self) -> (ReadHalf, WriteHalf)

Split a UnixStream into a read half and a write half, which can be used to read and write the stream concurrently.

See the module level documenation of split for more details.

Trait Implementations

impl AsRawFd for UnixStream

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl<'_> AsRef<UnixStream> for ReadHalf<'_>

fn as_ref(&self) -> &UnixStream

Performs the conversion.

impl<'_> AsRef<UnixStream> for WriteHalf<'_>

fn as_ref(&self) -> &UnixStream

Performs the conversion.

impl AsyncRead for UnixStream

unsafe fn prepare_uninitialized_buffer(&self, _: &mut [MaybeUninit<u8>]) -> bool

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out.

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

Attempts to read from the AsyncRead into buf.

fn poll_read_buf<B: BufMut>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize>> where
    Self: Sized, 

Pulls some bytes from this source into the specified BufMut, returning how many bytes were read.

impl AsyncWrite for UnixStream

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_flush(self: Pin<&mut Self>, _: &mut Context) -> Poll<Result<()>>

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

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

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

fn poll_write_buf<B: Buf>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize, Error>> where
    Self: Sized, 

Writes a Buf into this value, returning how many bytes were written.

impl Debug for UnixStream

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

Formats the value using the given formatter.

impl TryFrom<UnixStream> for UnixStream

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: UnixStream) -> Result<Self, Self::Error>

Consumes value, returning the mio I/O object.

See PollEvented::into_inner for more details about resource deregistration that happens during the call.

impl TryFrom<UnixStream> for UnixStream

type Error = Error

The type returned in the event of a conversion error.

fn try_from(stream: UnixStream) -> Result<Self>

Consumes stream, returning the tokio I/O object.

This is equivalent to UnixStream::from_std(stream).
