Struct NetworkSwitch 

pub struct NetworkSwitch { /* private fields */ }

The L2 switch. Owns ports grouped by network, runs a forwarding loop.

Implementations

impl NetworkSwitch

pub fn new() -> Self

pub fn add_port( &self, network_id: &str, _label: &str, ) -> Result<VmSocketEndpoint>

Add a port to a network. Returns the VM’s end of the socketpair fd.

Creates a Unix SOCK_DGRAM socketpair. One end is kept by the switch (for reading/writing Ethernet frames), the other is returned so the caller can pass it to VZFileHandleNetworkDeviceAttachment.

pub fn start(&self) -> Result<()>

Start the forwarding loop on a background thread.

Uses poll(2) to watch all switch-side fds. When a frame arrives on any port, it’s forwarded according to learning-bridge rules.

pub fn stop(&self)

Stop the forwarding loop.

Trait Implementations

impl Default for NetworkSwitch

fn default() -> Self

Returns the “default value” for a type.

impl Drop for NetworkSwitch

fn drop(&mut self)

Executes the destructor for this type.
