Struct MemoryLimit 

pub struct MemoryLimit {
    pub bytes: u64,
    pub source: LimitSource,
}

The memory this process may use, and why that number.

Fields

bytes: u64

source: LimitSource

Implementations

impl MemoryLimit

pub fn read() -> Option<MemoryLimit>

This process’s limit: /proc/meminfo, /proc/self/cgroup, /sys/fs/cgroup. None when neither the box nor a cgroup can be read.

pub fn read_from( meminfo: &Path, cgroup_dir: Option<&Path>, ) -> Option<MemoryLimit>

The same rule over named files: what a test hands a fake box and a fake cgroup.

pub fn cgroup_dir(&self) -> Option<&Path>

The cgroup directory when the limit is a cgroup’s.

pub fn words(&self) -> String

What the limit is, in words: 16.0G (MemTotal), 6.0G (cgroup memory.max).
