Struct CpuQuota 

pub struct CpuQuota { /* private fields */ }

A cgroup CPU quota: how much CPU time the group may use per period.

Constructed only from a period that can produce a meaningful ratio, so there is no representable quota that divides by zero or yields a non-finite core count. An unlimited group is not a CpuQuota at all — it is MetricState::Unsupported on CpuSnapshot::cgroup_quota, mirroring how memory.max reading max becomes unsupported rather than u64::MAX.

Both raw figures are kept, not just the derived core count: someone debugging why their container is being throttled wants to see the 100000 200000 they configured, and deriving it back from 2.0 would lose the period.

Implementations

impl CpuQuota

pub fn new(quota_us: u64, period_us: u64) -> Option<Self>

Builds a quota, or None when it could not describe a real ceiling.

Rejects a zero period — division by zero — and a ratio that is not finite. A zero quota is accepted: a group allowed no CPU time at all is a real, if hostile, configuration, and reporting it as absent would hide it.

pub fn cores(&self) -> f32

The ceiling as a number of CPUs, e.g. 1.5.

pub const fn quota_us(&self) -> u64

Microseconds of CPU time allowed per period, as configured.

pub const fn period_us(&self) -> u64

The accounting period in microseconds, as configured.
