Struct std::net::TcpStream1.0.0 [] [src]

pub struct TcpStream(_);

A structure which represents a TCP stream between a local socket and a remote socket.

The socket will be closed when the value is dropped.

Examples

use std::io::prelude::*;
use std::net::TcpStream;

{
    let mut stream = TcpStream::connect("127.0.0.1:34254").unwrap();

    // ignore the Result
    let _ = stream.write(&[1]);
    let _ = stream.read(&mut [0; 128]); // ignore here too
} // the stream is closed hereRun

Methods

impl TcpStream
[src]

Opens a TCP connection to a remote host.

addr is an address of the remote host. Anything which implements ToSocketAddrs trait can be supplied for the address; see this trait documentation for concrete examples. In case ToSocketAddrs::to_socket_addrs() returns more than one entry, then the first valid and reachable address is used.

Examples

use std::net::TcpStream;

if let Ok(stream) = TcpStream::connect("127.0.0.1:8080") {
    println!("Connected to the server!");
} else {
    println!("Couldn't connect to server...");
}Run

Returns the socket address of the remote peer of this TCP connection.

Examples

use std::net::{Ipv4Addr, SocketAddr, SocketAddrV4, TcpStream};

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
assert_eq!(stream.peer_addr().unwrap(),
           SocketAddr::V4(SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 8080)));Run

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

Examples

use std::net::{Ipv4Addr, SocketAddr, SocketAddrV4, TcpStream};

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
assert_eq!(stream.local_addr().unwrap(),
           SocketAddr::V4(SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 8080)));Run

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

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

Examples

use std::net::{Shutdown, TcpStream};

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.shutdown(Shutdown::Both).expect("shutdown call failed");Run

Creates a new independently owned handle to the underlying socket.

The returned TcpStream 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::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
let stream_clone = stream.try_clone().expect("clone failed...");Run

Sets the read timeout to the timeout specified.

If the value specified is None, then read() calls will block indefinitely. It is an error to pass the zero Duration to this method.

Note

Platforms may return a different error code whenever a read times out as a result of setting this option. For example Unix typically returns an error of the kind WouldBlock, but Windows may return TimedOut.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_read_timeout(None).expect("set_read_timeout call failed");Run

Sets the write timeout to the timeout specified.

If the value specified is None, then write() calls will block indefinitely. It is an error to pass the zero Duration to this method.

Note

Platforms may return a different error code whenever a write times out as a result of setting this option. For example Unix typically returns an error of the kind WouldBlock, but Windows may return TimedOut.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_write_timeout(None).expect("set_write_timeout call failed");Run

Returns the read timeout of this socket.

If the timeout is None, then read() calls will block indefinitely.

Note

Some platforms do not provide access to the current timeout.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_read_timeout(None).expect("set_read_timeout call failed");
assert_eq!(stream.read_timeout().unwrap(), None);Run

Returns the write timeout of this socket.

If the timeout is None, then write() calls will block indefinitely.

Note

Some platforms do not provide access to the current timeout.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_write_timeout(None).expect("set_write_timeout call failed");
assert_eq!(stream.write_timeout().unwrap(), None);Run

Sets the value of the TCP_NODELAY option on this socket.

If set, this option disables the Nagle algorithm. This means that segments are always sent as soon as possible, even if there is only a small amount of data. When not set, data is buffered until there is a sufficient amount to send out, thereby avoiding the frequent sending of small packets.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_nodelay(true).expect("set_nodelay call failed");Run

Gets the value of the TCP_NODELAY option on this socket.

For more information about this option, see set_nodelay.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_nodelay(true).expect("set_nodelay call failed");
assert_eq!(stream.nodelay().unwrap_or(false), true);Run

Sets the value for the IP_TTL option on this socket.

This value sets the time-to-live field that is used in every packet sent from this socket.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_ttl(100).expect("set_ttl call failed");Run

Gets the value of the IP_TTL option for this socket.

For more information about this option, see set_ttl.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_ttl(100).expect("set_ttl call failed");
assert_eq!(stream.ttl().unwrap_or(0), 100);Run

Get the value of the SO_ERROR option on this socket.

This will retrieve the stored error in the underlying socket, clearing the field in the process. This can be useful for checking errors between calls.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.take_error().expect("No error was expected...");Run

Moves this TCP stream into or out of nonblocking mode.

On Unix this corresponds to calling fcntl, and on Windows this corresponds to calling ioctlsocket.

Examples

use std::net::TcpStream;

let stream = TcpStream::connect("127.0.0.1:8080")
                       .expect("Couldn't connect to the server...");
stream.set_nonblocking(true).expect("set_nonblocking call failed");Run
