Struct tokio::net::UnixStream

pub struct UnixStream { /* fields omitted */ }

This is supported on crate feature net only.

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.

Implementations

impl UnixStream

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

This is supported on crate feature net only.

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>

This is supported on crate feature net only.

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 Runtime::enter function.

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

This is supported on crate feature net only.

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>

This is supported on crate feature net only.

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

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

This is supported on crate feature net only.

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

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

This is supported on crate feature net only.

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

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

This is supported on crate feature net only.

Returns the value of the SO_ERROR option.

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

This is supported on crate feature net only.

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<'a>(&'a mut self) -> (ReadHalf<'a>, WriteHalf<'a>)

This is supported on crate feature net only.

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

This method is more efficient than into_split, but the halves cannot be moved into independently spawned tasks.

pub fn into_split(self) -> (OwnedReadHalf, OwnedWriteHalf)

This is supported on crate feature net only.

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

Unlike split, the owned halves can be moved to separate tasks, however this comes at the cost of a heap allocation.

Note: Dropping the write half will shut down the write half of the stream. This is equivalent to calling shutdown(Write) on the UnixStream.

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 AsRef<UnixStream> for OwnedReadHalf

fn as_ref(&self) -> &UnixStream

Performs the conversion.

impl AsRef<UnixStream> for OwnedWriteHalf

fn as_ref(&self) -> &UnixStream

Performs the conversion.

impl AsyncRead for UnixStream

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

Attempts to read from the AsyncRead into buf.

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.

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(stream: UnixStream) -> Result<Self>

Consumes stream, returning the tokio I/O object.

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