Struct RawCommandClient 

pub struct RawCommandClient { /* private fields */ }

Available on crate feature net only.

An unrestricted command-channel UDP client. Raw operations intentionally live on this distinct type. The safe client can be converted into it only by consuming the idle client with CommandClient::into_raw. A raw client can transmit arbitrary bytes, receive from any peer, and change socket options; those operations carry no command validation or transaction guarantee.

Implementations

impl RawCommandClient

pub fn bind(interface: Ipv4Addr, server: SocketAddrV4) -> Result<Self>

Binds an unrestricted command socket to interface and records the default destination server.

Errors

Returns the operating-system error from binding the socket.

pub fn server(&self) -> SocketAddr

The configured default destination.

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

The local address selected for this socket.

Errors

Returns the operating-system error from querying the socket.

pub fn send(&self, datagram: &[u8]) -> Result<usize>

Sends arbitrary bytes to the configured default destination.

Errors

Returns the operating-system send error.

pub fn send_to(&self, datagram: &[u8], destination: SocketAddr) -> Result<usize>

Sends arbitrary bytes to any destination.

Errors

Returns the operating-system send error.

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

Receives arbitrary bytes and returns their source address.

Errors

Returns the operating-system receive error.

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

Changes raw receive blocking behavior.

Errors

Returns the operating-system error from changing the socket mode.

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

Changes the raw receive timeout.

Errors

Returns the operating-system error from changing the timeout.

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

Changes the raw send timeout.

Errors

Returns the operating-system error from changing the timeout.

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

Reads the current raw receive timeout.

Errors

Returns the operating-system error from querying the timeout.

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

Reads the current raw send timeout.

Errors

Returns the operating-system error from querying the timeout.
