# Struct std::os::unix::net::UnixStream 1.10.0[−][src]

    pub struct UnixStream(_);

This is supported on Unix only.

A Unix stream socket.

# Examples

    use std::os::unix::net::UnixStream;
    use std::io::prelude::*;

    let mut stream = UnixStream::connect("/path/to/my/socket").unwrap();
    stream.write_all(b"hello world").unwrap();
    let mut response = String::new();
    stream.read_to_string(&mut response).unwrap();
    println!("{}", response);Run

## Methods

###

`impl UnixStream`

[src]

####

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

[src]

This is supported on Unix only.

Connects to the socket named by `path`.

# Examples

    use std::os::unix::net::UnixStream;

    let socket = match UnixStream::connect("/tmp/sock") {
        Ok(sock) => sock,
        Err(e) => {
            println!("Couldn't connect: {:?}", e);
            return
        }
    };Run

####

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

[src]

This is supported on Unix only.

Creates an unnamed pair of connected sockets.

Returns two `UnixStream`s which are connected to each other.

# Examples

    use std::os::unix::net::UnixStream;

    let (sock1, sock2) = match UnixStream::pair() {
        Ok((sock1, sock2)) => (sock1, sock2),
        Err(e) => {
            println!("Couldn't create a pair of sockets: {:?}", e);
            return
        }
    };Run

####

`pub fn try_clone(&self) -> Result<UnixStream>`

[src]

This is supported on Unix only.

Creates a new independently owned handle to the underlying socket.

The returned `UnixStream` is a reference to the same stream that this object references. Both handles will read and write the same stream of data, and options set on one stream will be propagated to the other stream.

# Examples

    use std::os::unix::net::UnixStream;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    let sock_copy = socket.try_clone().expect("Couldn't clone socket");Run

####

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

[src]

This is supported on Unix only.

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

# Examples

    use std::os::unix::net::UnixStream;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    let addr = socket.local_addr().expect("Couldn't get local address");Run

####

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

[src]

This is supported on Unix only.

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

# Examples

    use std::os::unix::net::UnixStream;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    let addr = socket.peer_addr().expect("Couldn't get peer address");Run

####

`pub fn set_read_timeout(&self, timeout: Option<Duration>) -> Result<()>`

[src]

This is supported on Unix only.

Sets the read timeout for the socket.

If the provided value is `None`, then `read` calls will block indefinitely. An `Err` is returned if the zero `Duration` is passed to this method.

# Examples

    use std::os::unix::net::UnixStream;
    use std::time::Duration;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    socket.set_read_timeout(Some(Duration::new(1, 0))).expect("Couldn't set read timeout");Run

An `Err` is returned if the zero `Duration` is passed to this method:

    use std::io;
    use std::os::unix::net::UnixStream;
    use std::time::Duration;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    let result = socket.set_read_timeout(Some(Duration::new(0, 0)));
    let err = result.unwrap_err();
    assert_eq!(err.kind(), io::ErrorKind::InvalidInput)Run

####

`pub fn set_write_timeout(&self, timeout: Option<Duration>) -> Result<()>`

[src]

This is supported on Unix only.

Sets the write timeout for the socket.

If the provided value is `None`, then `write` calls will block indefinitely. An `Err` is returned if the zero `Duration` is passed to this method.

# Examples

    use std::os::unix::net::UnixStream;
    use std::time::Duration;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    socket.set_write_timeout(Some(Duration::new(1, 0))).expect("Couldn't set write timeout");Run

An `Err` is returned if the zero `Duration` is passed to this method:

    use std::io;
    use std::net::UdpSocket;
    use std::time::Duration;

    let socket = UdpSocket::bind("127.0.0.1:34254").unwrap();
    let result = socket.set_write_timeout(Some(Duration::new(0, 0)));
    let err = result.unwrap_err();
    assert_eq!(err.kind(), io::ErrorKind::InvalidInput)Run

####

`pub fn read_timeout(&self) -> Result<Option<Duration>>`

[src]

This is supported on Unix only.

Returns the read timeout of this socket.

# Examples

    use std::os::unix::net::UnixStream;
    use std::time::Duration;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    socket.set_read_timeout(Some(Duration::new(1, 0))).expect("Couldn't set read timeout");
    assert_eq!(socket.read_timeout().unwrap(), Some(Duration::new(1, 0)));Run

####

`pub fn write_timeout(&self) -> Result<Option<Duration>>`

[src]

This is supported on Unix only.

Returns the write timeout of this socket.

# Examples

    use std::os::unix::net::UnixStream;
    use std::time::Duration;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    socket.set_write_timeout(Some(Duration::new(1, 0))).expect("Couldn't set write timeout");
    assert_eq!(socket.write_timeout().unwrap(), Some(Duration::new(1, 0)));Run

####

`pub fn set_nonblocking(&self, nonblocking: bool) -> Result<()>`

[src]

This is supported on Unix only.

Moves the socket into or out of nonblocking mode.

# Examples

    use std::os::unix::net::UnixStream;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    socket.set_nonblocking(true).expect("Couldn't set nonblocking");Run

####

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

[src]

This is supported on Unix only.

Returns the value of the `SO_ERROR` option.

# Examples

    use std::os::unix::net::UnixStream;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    if let Ok(Some(err)) = socket.take_error() {
        println!("Got error: {:?}", err);
    }Run

# Platform specific

On Redox this always returns None.

####

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

[src]

This is supported on Unix 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`).

# Examples

    use std::os::unix::net::UnixStream;
    use std::net::Shutdown;

    let socket = UnixStream::connect("/tmp/sock").unwrap();
    socket.shutdown(Shutdown::Both).expect("shutdown function failed");Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
