std::process Cgroups?

[SethDusek]

Could it be possible to have cgroup support for std::process? Like a linux-specific trait so that you can limit certain things of processes for example:

Command::new("somecommand")
.arg("somearg")
.cgroup("somegroup:/somesubgroup")
.spawn()

It'd be really useful in certain stuff such as timeouts and memory limits, etc

Thanks for the report! A feature request to add support for cgroups (e.g. a platform-specific extension) currently belongs over in the rust-lang/rfcs repo, but you may also be interested in the recently-approved CommandExt::before_exec function which should allow this as well (e.g. arbitrary code execution following just before an exec.

If the before_exec doesn't work out, could you open an issue against rust-lang/rfcs? Thanks!
