cgroups-rs
Native Rust library for managing control groups under Linux
Right now the crate only support the original, V1 hierarchy, however support is planned for the Unified hierarchy.
Examples
Create a control group using the builder pattern
// Acquire a handle for the V1 cgroup hierarchy.
let hier = V1 new;
// 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 = new
.cpu
.shares
.done
.build;
// 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: &CpuController = cg.controller_of.unwrap;
cpus.add_task;
// [...]
// 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.
