Struct MemoryCapacity 

pub struct MemoryCapacity {
    pub physical_bytes: Option<u64>,
    pub available_bytes: Option<u64>,
    pub limit_bytes: Option<u64>,
    pub limit_source: &'static str,
    pub used_in_limit_bytes: Option<u64>,
}

The machine’s memory and this process’s limit. Unavailable figures are None.

Fields

physical_bytes: Option<u64>

Physical memory installed.

available_bytes: Option<u64>

Memory available without paging: MemAvailable on Linux, free plus inactive plus purgeable pages on macOS, ullAvailPhys on Windows.

limit_bytes: Option<u64>

The lowest of a cgroup or job limit and the physical total.

limit_source: &'static str

What set limit_bytes: cgroup-v2, cgroup-v1, job or physical.

used_in_limit_bytes: Option<u64>

Usage charged against a cgroup limit; None for physical and job limits.

impl MemoryCapacity

pub fn effective_limit(&self) -> Option<u64>

The limit, else the physical total.

pub fn headroom(&self) -> Option<u64>

The lower of available memory and the headroom left under the limit.
