Struct TcpStream 

pub struct TcpStream { /* private fields */ }

RAII wrapper around a TCP (stream) socket.

Uses inline storage for the socket backend, so no heap/zero-heap split is needed. The handle is derived from &self.storage at each call to avoid dangling self-referential pointers after Rust moves the struct.

Implementations

impl TcpStream

pub fn new() -> Result<Self>

Open a new TCP socket.

Errors

Returns an error if the RTOS cannot open the socket.

pub fn connect(&self, addr: &Address, timeout_ms: u32) -> Result<()>

Connect to a remote address with a timeout.

Errors

Returns an error if the connection fails or times out.

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

Send data on the connected socket.

Returns the number of bytes actually sent.

Errors

Returns an error if the send fails.

pub fn recv(&self, buf: &mut [u8], timeout_ms: u32) -> Result<usize>

Receive data from the connected socket.

Returns the number of bytes received.

Errors

Returns an error if the receive fails or times out.
