pub fn process_usage_with_threads() -> Result<ProcessThreads>Expand description
Resource usage of the current process and its per-thread breakdown, from one snapshot.
More expensive than process_usage (it opens each thread to read its name and start
address), so it is for benches and diagnosis. A thread that exits while the names are read
keeps its counters and has no name. Fails when the host cannot list threads (Windows when the
process table is unreadable, other Unix targets with ErrorKind::Unsupported).
