Struct rtnetlink::LinkAddRequest

pub struct LinkAddRequest { /* private fields */ }

A request to create a new link. This is equivalent to the ip link add commands.

A few methods for common actions (creating a veth pair, creating a vlan interface, etc.) are provided, but custom requests can be made using the message_mut() accessor.

Implementations

impl LinkAddRequest

pub async fn execute(self) -> Result<(), Error>

Execute the request.

pub fn message_mut(&mut self) -> &mut LinkMessage

Return a mutable reference to the request message.

Example

Let’s say we want to create a vlan interface on a link with id 6. By default, the vlan() method would create a request with the IFF_UP link set, so that the interface is up after creation. If we want to create a interface tha tis down by default we could do:

use futures::Future;
use rtnetlink::{Handle, new_connection, packet::IFF_UP};

async fn run(handle: Handle) -> Result<(), String> {
    let vlan_id = 100;
    let link_id = 6;
    let mut request = handle.link().add().vlan("my-vlan-itf".into(), link_id, vlan_id);
    // unset the IFF_UP flag before sending the request
    request.message_mut().header.flags &= !IFF_UP;
    request.message_mut().header.change_mask &= !IFF_UP;
    // send the request
    request.execute().await.map_err(|e| format!("{}", e))
}

pub fn dummy(self, name: String) -> Self

Create a dummy link. This is equivalent to ip link add NAME type dummy.

pub fn veth(self, name: String, peer_name: String) -> Self

Create a veth pair. This is equivalent to ip link add NAME1 type veth peer name NAME2.

pub fn vlan(self, name: String, index: u32, vlan_id: u16) -> Self

Create VLAN on a link. This is equivalent to ip link add link LINK name NAME type vlan id VLAN_ID, but instead of specifying a link name (LINK), we specify a link index.

pub fn macvlan(self, name: String, index: u32, mode: u32) -> Self

Create macvlan on a link. This is equivalent to ip link add name NAME link LINK type macvlan mode MACVLAN_MODE, but instead of specifying a link name (LINK), we specify a link index. The MACVLAN_MODE is an integer consisting of flags from MACVLAN_MODE (netlink-packet-route/src/rtnl/constants.rs) being: _PRIVATE, _VEPA, _BRIDGE, _PASSTHRU, _SOURCE, which can be combined.

pub fn vxlan(self, name: String, vni: u32) -> VxlanAddRequest

Create a VxLAN This is equivalent to ip link add name NAME type vxlan id VNI, it returns a VxlanAddRequest to further customize the vxlan interface creation.

pub fn bridge(self, name: String) -> Self

Create a new bridge. This is equivalent to ip link add link NAME type bridge.

pub fn replace(self) -> Self

Replace existing matching link.
