sourceimpl CgroupReader
impl CgroupReader
pub fn new(root: PathBuf) -> Result<CgroupReader>
pub fn new_with_relative_path(
root: PathBuf,
relative_path: PathBuf
) -> Result<CgroupReader>
pub fn root() -> Result<CgroupReader>
sourcepub fn name(&self) -> &Path
pub fn name(&self) -> &Path
Returns the cgroup name (e.g. the path relative to the cgroup root) Invoking this on the root cgroup will return an empty path
pub fn read_inode_number(&self) -> Result<u64>
sourcepub fn read_memory_current(&self) -> Result<u64>
pub fn read_memory_current(&self) -> Result<u64>
Read memory.current - returning current cgroup memory consumption in bytes
sourcepub fn read_memory_high(&self) -> Result<Option<i64>>
pub fn read_memory_high(&self) -> Result<Option<i64>>
Read memory.high - returning memory.high consumption in bytes Will return -1 if the content is max Will return None if the file is missing
sourcepub fn read_memory_swap_current(&self) -> Result<u64>
