Struct UnixStream

pub struct UnixStream { /* private fields */ }

A non-blocking Unix stream socket with support for passing RawFd.

Implementations

impl UnixStream

pub fn connect(path: impl AsRef<Path>) -> Result<UnixStream>

Connects to the socket named by path.

Note that this is synchronous.

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

Creates an unnamed pair of connected sockets.

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 connections.

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 the 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).

Trait Implementations

impl AsRawFd for UnixStream

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Debug for UnixStream

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

Formats the value using the given formatter.

impl DequeueFd for UnixStream

fn dequeue(&mut self) -> Option<RawFd>

Dequeue a previously transmitted RawFd.

impl EnqueueFd for UnixStream

fn enqueue(&mut self, fd: &impl AsRawFd) -> Result<(), QueueFullError>

Enqueue fd for later transmission to a different process.

impl Evented for UnixStream

fn register( &self, registry: &Poll, token: Token, interests: Ready, opts: PollOpt, ) -> Result<()>

Register self with the given Poll instance.

fn reregister( &self, registry: &Poll, token: Token, interests: Ready, opts: PollOpt, ) -> Result<()>

Re-register self with the given Poll instance.

fn deregister(&self, registry: &Poll) -> Result<()>

Deregister self from the given Poll instance

impl FromRawFd for UnixStream

Create a UnixStream from a RawFd.

This does not change the RawFd into non-blocking mode. It assumes that any such required change has already been done.

unsafe fn from_raw_fd(fd: RawFd) -> Self

Constructs a new instance of Self from the given raw file descriptor.

impl IntoRawFd for UnixStream

fn into_raw_fd(self) -> RawFd

Consumes this object, returning the raw underlying file descriptor.

impl Read for UnixStream

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Reads all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Reads all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Reads the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.

impl TryFrom<UnixStream> for UnixStream

type Error = Error

The type returned in the event of a conversion error.

fn try_from(inner: StdUnixStream) -> Result<UnixStream>

Performs the conversion.

impl Write for UnixStream

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

Writes a buffer into this writer, returning how many bytes were written.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize>

Like write, except that it writes from a slice of buffers.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
