[][src]Struct tokio_core::net::TcpStream

pub struct TcpStream { /* fields omitted */ }

An I/O object representing a TCP stream connected to a remote endpoint.

A TCP stream can either be created by connecting to an endpoint or by accepting a connection from a listener. Inside the stream is access to the raw underlying I/O object as well as streams for the read/write notifications on the stream itself.

Methods

impl TcpStream[src]

pub fn connect(addr: &SocketAddr, handle: &Handle) -> TcpStreamNew[src]

Create a new TCP stream connected to the specified address.

This function will create a new TCP socket and attempt to connect it to the addr provided. The returned future will be resolved once the stream has successfully connected. If an error happens during the connection or during the socket creation, that error will be returned to the future instead.

pub fn connect2(addr: &SocketAddr) -> TcpStreamNew[src]

Create a new TCP stream connected to the specified address.

This is the same as connect, but uses the default reactor instead of taking an explicit &Handle.

pub fn from_stream(stream: TcpStream, handle: &Handle) -> Result<TcpStream>[src]

Create a new TcpStream from a net::TcpStream.

This function will convert a TCP stream in the standard library to a TCP stream ready to be used with the provided event loop handle. The object returned is associated with the event loop and ready to perform I/O.

pub fn connect_stream(
    stream: TcpStream,
    addr: &SocketAddr,
    handle: &Handle
) -> Box<dyn Future<Item = TcpStream, Error = Error> + Send>
[src]

Creates a new TcpStream from the pending socket inside the given std::net::TcpStream, connecting it to the address specified.

This constructor allows configuring the socket before it's actually connected, and this function will transfer ownership to the returned TcpStream if successful. An unconnected TcpStream can be created with the net2::TcpBuilder type (and also configured via that route).

The platform specific behavior of this function looks like:

  • On Unix, the socket is placed into nonblocking mode and then a connect call is issued.

  • On Windows, the address is stored internally and the connect operation is issued when the returned TcpStream is registered with an event loop. Note that on Windows you must bind a socket before it can be connected, so if a custom TcpBuilder is used it should be bound (perhaps to INADDR_ANY) before this method is called.

pub fn poll_read(&self) -> Async<()>[src]

Test whether this socket is ready to be read or not.

If the socket is not readable then the current task is scheduled to get a notification when the socket does become readable. That is, this is only suitable for calling in a Future::poll method and will automatically handle ensuring a retry once the socket is readable again.

pub fn poll_write(&self) -> Async<()>[src]

Test whether this socket is ready to be written to or not.

If the socket is not writable then the current task is scheduled to get a notification when the socket does become writable. That is, this is only suitable for calling in a Future::poll method and will automatically handle ensuring a retry once the socket is writable again.

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

Returns the local address that this stream is bound to.

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

Returns the remote address that this stream is connected to.

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

Receives data on the socket from the remote address to which it is connected, without removing that data from the queue. On success, returns the number of bytes peeked.

Successive calls return the same data. This is accomplished by passing MSG_PEEK as a flag to the underlying recv system call.

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

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).

pub fn set_nodelay(&self, nodelay: bool) -> Result<()>[src]

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.

pub fn nodelay(&self) -> Result<bool>[src]

Gets the value of the TCP_NODELAY option on this socket.

For more information about this option, see set_nodelay.

pub fn set_recv_buffer_size(&self, size: usize) -> Result<()>[src]

Sets the value of the SO_RCVBUF option on this socket.

Changes the size of the operating system's receive buffer associated with the socket.

pub fn recv_buffer_size(&self) -> Result<usize>[src]

Gets the value of the SO_RCVBUF option on this socket.

For more information about this option, see set_recv_buffer_size.

pub fn set_send_buffer_size(&self, size: usize) -> Result<()>[src]

Sets the value of the SO_SNDBUF option on this socket.

Changes the size of the operating system's send buffer associated with the socket.

pub fn send_buffer_size(&self) -> Result<usize>[src]

Gets the value of the SO_SNDBUF option on this socket.

For more information about this option, see set_send_buffer.

pub fn set_keepalive(&self, keepalive: Option<Duration>) -> Result<()>[src]

Sets whether keepalive messages are enabled to be sent on this socket.

On Unix, this option will set the SO_KEEPALIVE as well as the TCP_KEEPALIVE or TCP_KEEPIDLE option (depending on your platform). On Windows, this will set the SIO_KEEPALIVE_VALS option.

If None is specified then keepalive messages are disabled, otherwise the duration specified will be the time to remain idle before sending a TCP keepalive probe.

Some platforms specify this value in seconds, so sub-second specifications may be omitted.

pub fn keepalive(&self) -> Result<Option<Duration>>[src]

Returns whether keepalive messages are enabled on this socket, and if so the duration of time between them.

For more information about this option, see set_keepalive.

pub fn set_ttl(&self, ttl: u32) -> Result<()>[src]

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.

pub fn ttl(&self) -> Result<u32>[src]

Gets the value of the IP_TTL option for this socket.

For more information about this option, see set_ttl.

pub fn set_only_v6(&self, only_v6: bool) -> Result<()>[src]

Sets the value for the IPV6_V6ONLY option on this socket.

If this is set to true then the socket is restricted to sending and receiving IPv6 packets only. In this case two IPv4 and IPv6 applications can bind the same port at the same time.

If this is set to false then the socket can be used to send and receive packets from an IPv4-mapped IPv6 address.

pub fn only_v6(&self) -> Result<bool>[src]

Gets the value of the IPV6_V6ONLY option for this socket.

For more information about this option, see set_only_v6.

pub fn set_linger(&self, dur: Option<Duration>) -> Result<()>[src]

Sets the linger duration of this socket by setting the SO_LINGER option

pub fn linger(&self) -> Result<Option<Duration>>[src]

reads the linger duration for this socket by getting the SO_LINGER option
