Struct cgroups_rs::freezer::FreezerController [−][src]
A controller that allows controlling the freezer subsystem of a Cgroup.
In essence, this subsystem allows the user to freeze and thaw (== “un-freeze”) the processes in the control group. This is done transparently so that neither the parent, nor the children of the processes can observe the freeze.
Note that if the control group is currently in the Frozen or Freezing state, then no
processes can be added to it.
Implementations
impl FreezerController[src]
pub fn new(root: PathBuf, v2: bool) -> Self[src]
Contructs a new FreezerController with root serving as the root of the control group.
pub fn freeze(&self) -> Result<()>[src]
Freezes the processes in the control group.
pub fn thaw(&self) -> Result<()>[src]
Thaws, that is, unfreezes the processes in the control group.
pub fn state(&self) -> Result<FreezerState>[src]
Retrieve the state of processes in the control group.
