Trait CommandCgroupExt 

pub trait CommandCgroupExt {
    // Required method
    fn join_cgroup(&mut self, cgroup_procs: Arc<CString>) -> Result<(), Error>;
}

Available on Unix only.

Extension trait for moving a command into a cgroup before it runs.

Required Methods

fn join_cgroup(&mut self, cgroup_procs: Arc<CString>) -> Result<(), Error>

Arranges for the command to write 0 to cgroup_procs, a cgroup v2’s cgroup.procs file, after it is forked and before it runs its program, which moves it into that cgroup.

Errors

None here: a child that cannot open or write the file fails its spawn.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
