Available on crate feature resource only.

Get usage information for a process, its children or the current thread

Real time information can be obtained for either the current process or (in some systems) thread, but information about children processes is only provided for those that have terminated and been waited for (see super::wait::wait).

Some information may be missing depending on the platform, and the way information is provided for children may also vary. Check the manuals for details.
