Struct cgroups_rs::hugetlb::HugeTlbController[][src]

pub struct HugeTlbController { /* fields omitted */ }

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

In essence, using this controller it is possible to limit the use of hugepages in the tasks of the control group.

Implementations

impl HugeTlbController[src]

pub fn new(root: PathBuf, v2: bool) -> Self[src]

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

pub fn size_supported(&self, hugetlb_size: &str) -> bool[src]

Whether the system supports hugetlb_size hugepages.

pub fn get_sizes(&self) -> Vec<String>[src]

pub fn failcnt(&self, hugetlb_size: &str) -> Result<u64>[src]

Check how many times has the limit of hugetlb_size hugepages been hit.

pub fn limit_in_bytes(&self, hugetlb_size: &str) -> Result<u64>[src]

Get the limit (in bytes) of how much memory can be backed by hugepages of a certain size (hugetlb_size).

pub fn usage_in_bytes(&self, hugetlb_size: &str) -> Result<u64>[src]

Get the current usage of memory that is backed by hugepages of a certain size (hugetlb_size).

pub fn max_usage_in_bytes(&self, hugetlb_size: &str) -> Result<u64>[src]

Get the maximum observed usage of memory that is backed by hugepages of a certain size (hugetlb_size).

pub fn set_limit_in_bytes(&self, hugetlb_size: &str, limit: u64) -> Result<()>[src]

Set the limit (in bytes) of how much memory can be backed by hugepages of a certain size (hugetlb_size).
