Implementations

impl TcpConnection

pub fn new(local: SocketAddr, remote: SocketAddr) -> Self

pub fn connect(&mut self) -> Result<(), KernelError>

Initiate connection (active open) – sends SYN via IP layer.

pub fn listen(&mut self) -> Result<(), KernelError>

Listen for connections (passive open)

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

Send data by segmenting into MSS-sized chunks.

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

Receive data from the connection’s receive buffer.

pub fn close(&mut self) -> Result<(), KernelError>

Close connection by sending FIN.
