Trait CgroupsCommandExt

pub trait CgroupsCommandExt {
    // Required method
    fn cgroups(&mut self, cgroups: &[impl AsRef<Cgroup>]) -> &mut Self;
}

This trait is designed to extend std::process::Command type with helpers for Cgroups.

Required Methods

fn cgroups(&mut self, cgroups: &[impl AsRef<Cgroup>]) -> &mut Self

Specifies the Cgroups the executed process will be put into on start.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl CgroupsCommandExt for Command

fn cgroups(&mut self, cgroups: &[impl AsRef<Cgroup>]) -> &mut Self

Specifies the Cgroups the executed process will be put into on start.

Example

let my_cgroup = cgroups_fs::CgroupName::new("my-cgroup");
let my_memory_cgroup = cgroups_fs::AutomanagedCgroup::init(&my_cgroup, "memory").unwrap();

use cgroups_fs::CgroupsCommandExt;
let output = std::process::Command::new("echo")
    .arg("Hello world")
    .cgroups(&[&my_memory_cgroup])
    .output()
    .expect("Failed to execute command");

println!(
    "The echo process used {} bytes of RAM.",
    my_memory_cgroup.get_value::<u64>("memory.max_usage_in_bytes").unwrap()
);
