Struct cgroups_rs::net_cls::NetClsController [−][src]
A controller that allows controlling the net_cls
subsystem of a Cgroup.
In esssence, using the net_cls
controller, one can attach a custom class to the network
packets emitted by the control group’s tasks. This can then later be used in iptables to have
custom firewall rules, QoS, etc.
Implementations
impl NetClsController
[src]
pub fn new(root: PathBuf) -> Self
[src]
Constructs a new NetClsController
with root
serving as the root of the control group.
pub fn set_class(&self, class: u64) -> Result<()>
[src]
Set the network class id of the outgoing packets of the control group’s tasks.
pub fn get_class(&self) -> Result<u64>
[src]
Get the network class id of the outgoing packets of the control group’s tasks.
