Struct Cgroup 

pub struct Cgroup { /* private fields */ }

Cgroup is a non-root cgroup in a cgroup hierarchy, and can have other Cgroups as children.

Implementations

impl Cgroup

pub fn new( id: u64, name: &FsStr, root: &Weak<CgroupRoot>, parent: Option<Weak<Cgroup>>, ) -> CgroupHandle

pub fn name(&self) -> &FsStr

Trait Implementations

impl CgroupOps for Cgroup

fn id(&self) -> u64

Returns the unique ID of the cgroup. ID of root cgroup is 0.

fn add_process(&self, thread_group: &ThreadGroup) -> Result<(), Errno>

Add a process to a cgroup. Errors if the cgroup has been deleted.

fn new_child(&self, name: &FsStr) -> Result<CgroupHandle, Errno>

Create a new sub-cgroup as a child of this cgroup. Errors if the cgroup is deleted, or a child with name already exists.

fn get_child(&self, name: &FsStr) -> Result<CgroupHandle, Errno>

Gets the child with name, errors if not found.

fn remove_child(&self, name: &FsStr) -> Result<CgroupHandle, Errno>

Remove a child from this cgroup and return it, if found. Errors if cgroup is deleted, or a child with name is not found.

fn get_children(&self) -> Result<Vec<CgroupHandle>, Errno>

Gets all children of this cgroup.

fn get_pids(&self, _kernel: &Kernel) -> Vec<pid_t>

Return all pids that belong to this cgroup.

fn kill(&self)

Kills all processes in the cgroup and its descendants.

fn is_populated(&self) -> bool

Whether the cgroup or any of its descendants have any processes.

fn freezer(&self) -> Option<&dyn FreezerOps>

Returns freezer ops if freezer controller is supported.

fn cpuset(&self) -> Option<&dyn CpusetOps>

Returns cpuset ops if cpuset controller is supported.

impl CpusetOps for Cgroup

fn cpuset_cpus(&self) -> Vec<u32>

Returns the cpuset cpus of the cgroup.

fn set_cpuset_cpus(&self, cpus: Vec<u32>)

Sets the cpuset cpus of the cgroup.

impl Debug for Cgroup

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FreezerOps for Cgroup

fn get_freezer_state(&self) -> CgroupFreezerState

Get the freezer self state and effective state.

fn freeze(&self)

Freeze all tasks in the cgroup.

fn thaw(&self)

Thaw all tasks in the cgroup.
