Function set_current_thread_name 

pub fn set_current_thread_name(name: &str)

Available on crate feature process only.

Sets the OS-level name of the calling thread, visible to tools like top -H, perf, samply, and /proc/<pid>/task/*/comm.

Linux truncates thread names to 15 bytes (16 with the NUL terminator); name is truncated to fit. Best-effort: a no-op on non-Linux platforms, and silently does nothing if the underlying syscall fails.
