Struct net2::TcpBuilder

pub struct TcpBuilder { /* fields omitted */ }

An “in progress” TCP socket which has not yet been connected or listened.

Allows configuration of a socket before one of these operations is executed.

Implementations

impl TcpBuilder

pub fn new_v4() -> Result<TcpBuilder>

Constructs a new TcpBuilder with the AF_INET domain, the SOCK_STREAM type, and with a protocol argument of 0.

Note that passing other kinds of flags or arguments can be done through the FromRaw{Fd,Socket} implementation.

pub fn new_v6() -> Result<TcpBuilder>

Constructs a new TcpBuilder with the AF_INET6 domain, the SOCK_STREAM type, and with a protocol argument of 0.

Note that passing other kinds of flags or arguments can be done through the FromRaw{Fd,Socket} implementation.

pub fn bind<T>(&self, addr: T) -> Result<&TcpBuilder> where
    T: ToSocketAddrs, 

Binds this socket to the specified address.

This function directly corresponds to the bind(2) function on Windows and Unix.

pub fn listen(&self, backlog: i32) -> Result<TcpListener>

Mark a socket as ready to accept incoming connection requests using accept()

This function directly corresponds to the listen(2) function on Windows and Unix.

An error will be returned if listen or connect has already been called on this builder.

pub fn connect<T>(&self, addr: T) -> Result<TcpStream> where
    T: ToSocketAddrs, 

Initiate a connection on this socket to the specified address.

This function directly corresponds to the connect(2) function on Windows and Unix.

An error will be returned if listen or connect has already been called on this builder.

pub fn to_tcp_stream(&self) -> Result<TcpStream>

Converts this builder into a TcpStream

This function will consume the internal socket and return it re-wrapped as a TcpStream. An error will be returned if the internal socket has already been consumed from a successful call to connect, listen, etc.

pub fn to_tcp_listener(&self) -> Result<TcpListener>

Converts this builder into a TcpListener

This function will consume the internal socket and return it re-wrapped as a TcpListener. An error will be returned if the internal socket has already been consumed from a successful call to connect, listen, etc.

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

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

An error will be returned if listen or connect has already been called on this builder.

impl TcpBuilder

pub fn ttl(&self, ttl: u32) -> Result<&Self>

Sets the value for the IP_TTL option on this socket.

This is the same as TcpStreamExt::set_ttl.

pub fn only_v6(&self, only_v6: bool) -> Result<&Self>

Sets the value for the IPV6_V6ONLY option on this socket.

This is the same as TcpStreamExt::set_only_v6.

pub fn reuse_address(&self, reuse: bool) -> Result<&Self>

Set value for the SO_REUSEADDR option on this socket.

This indicates that further calls to bind may allow reuse of local addresses. For IPv4 sockets this means that a socket may bind even when there’s a socket already listening on this port.

pub fn get_reuse_address(&self) -> Result<bool>

Check the SO_REUSEADDR option on this socket.

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

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.

Trait Implementations

impl AsRawFd for TcpBuilder

fn as_raw_fd(&self) -> c_int

Extracts the raw file descriptor.

impl Debug for TcpBuilder

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

Formats the value using the given formatter.

impl FromRawFd for TcpBuilder

unsafe fn from_raw_fd(fd: c_int) -> TcpBuilder

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

impl UnixTcpBuilderExt for TcpBuilder

fn reuse_port(&self, reuse: bool) -> Result<&Self>

Set value for the SO_REUSEPORT option on this socket.

fn get_reuse_port(&self) -> Result<bool>

Check the value of the SO_REUSEPORT option on this socket.
