pub fn getrusage(who: UsageWho) -> Result<Usage>Expand description
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.
