Struct cgroups_rs::cpuacct::CpuAcctController[−][src]

pub struct CpuAcctController { /* fields omitted */ }

Expand description

A controller that allows controlling the cpuacct subsystem of a Cgroup.

In essence, this control group provides accounting (hence the name cpuacct) for CPU usage of the tasks in the control group.
