pub fn detect_memory_high() -> Option<u64>Available on crate feature
memory only.Expand description
Soft throttle ceiling: cgroup v2 memory.high.
The kernel begins aggressive reclaim and allocation throttling here, before
the hard memory.max OOM-kill, so an app that sheds before memory.high
avoids the throughput cliff. None when unset (max) or not cgroup v2.
