Struct Device 

#[non_exhaustive]
pub struct Device {
    pub total_memory: Option<u64>,
    pub available_memory: Option<u64>,
    pub cpus: usize,
}

The machine’s memory and CPUs, as the automatic budgets see them.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

total_memory: Option<u64>

Physical memory (lowered to a cgroup v2 memory.max), when known.

available_memory: Option<u64>

Memory available right now (available_memory), when known.

cpus: usize

CPUs this process may run on.
