Struct cgroups_rs::net_prio::NetPrioController

source · [−]

pub struct NetPrioController { /* private fields */ }

Expand description

A controller that allows controlling the net_prio subsystem of a Cgroup.

In essence, using net_prio one can set the priority of the packets emitted from the control group’s tasks. This can then be used to have QoS restrictions on certain control groups and thus, prioritizing certain tasks.

Implementations

source

impl NetPrioController

source

pub fn new(root: PathBuf) -> Self

Constructs a new NetPrioController with root serving as the root of the control group.

source

pub fn prio_idx(&self) -> u64

source

pub fn ifpriomap(&self) -> Result<HashMap<String, u64>>

A map of priorities for each network interface.

source

pub fn set_if_prio(&self, eif: &str, prio: u64) -> Result<()>

Set the priority of the network traffic on eif to be prio.
