cgroups-rs's Introduction

cgroups-rs

Native Rust library for managing control groups under Linux

Both v1 and v2 of cgroups are supported.

Examples

Create a control group using the builder pattern

use cgroups_rs::*;
use cgroups_rs::cgroup_builder::*;

// Acquire a handle for the cgroup hierarchy.
let hier = cgroups_rs::hierarchies::auto();

// Use the builder pattern (see the documentation to create the control group)
//
// This creates a control group named "example" in the V1 hierarchy.
    let cg: Cgroup = CgroupBuilder::new("example")
        .cpu()
        .shares(85)
        .done()
        .build(hier);

// Now `cg` is a control group that gets 85% of the CPU time in relative to
// other control groups.

// Get a handle to the CPU controller.
let cpus: &cgroups_rs::cpu::CpuController = cg.controller_of().unwrap();
cpus.add_task(&CgroupPid::from(1234u64));

// [...]

// Finally, clean up and delete the control group.
cg.delete();

// Note that `Cgroup` does not implement `Drop` and therefore when the
// structure is dropped, the Cgroup will stay around. This is because, later
// you can then re-create the `Cgroup` using `load()`. We aren't too set on
// this behavior, so it might change in the feature. Rest assured, it will be a
// major version change.
