Struct CgroupController 

pub struct CgroupController { /* private fields */ }

CgroupController is the main component in cgumi, and it should always be created first. All CgroupNode should be created by CgroupController.

Implementations

impl CgroupController

pub fn new( root: &str, request_func: Option<Box<dyn Fn(&PrivilegeOpType, &str) -> Result<(), Error>>>, ) -> Self

root is the cgroupv2 mountpoint, and request_func is an optional function that prompts users to run commands in root permission.

pub fn root(&self) -> &PathBuf

pub fn create_from_path( &self, name: &PathBuf, allow_exists: bool, ) -> Result<CgroupNode<'_>, CgroupError>

Create a CgroupNode from a relative path (name).

pub fn get_from_current(&self) -> Result<CgroupNode<'_>, CgroupError>

Get the CgroupNode from what current program is in.

pub fn create_from_node_path( &self, node: &CgroupNode<'_>, name: &PathBuf, allow_exists: bool, ) -> Result<CgroupNode<'_>, CgroupError>

Create a CgroupNode from a node and a name relative to the node.

pub fn get_root_node(&self) -> Result<CgroupNode<'_>, CgroupError>

Get the root as a CgroupNode.

pub fn create_systemd_cgroup( &self, name: &str, ) -> Result<CgroupNode<'_>, CgroupError>

Create a systemd scope, and therefore get a cgroup node from that.
