TCP-based vsock backend.

Maps vsock ports to TCP ports for host-side handling.

Implementations

impl TcpBackend

pub fn new(guest_cid: u64, base_port: u16) -> Self

Creates a new TCP backend.

pub fn listen(&self, port: u32) -> Result<()>

Listens on a vsock port.

pub fn accept(&self, port: u32) -> Result<Option<VsockAddr>>

Accepts a pending connection.
