Struct Target

pub struct Target { /* private fields */ }

Event target, the process (or cgroup) and CPU to monitor.

To create an event target, combine these types in a tuple: Proc (or Cgroup), Cpu and All.

For example, we want to monitor process with pid 12345 on all CPUs: (Pid(12345), Cpu::ALL). The order of types in the tuples is not senstive because we impl Into<Target> for these swapped tuples, e.g. (Cpu::ALL, Pid(12345)) has the same semantics as the example above.

This design limits what we can monitor at compile time. For example, the kernel not support monitoring any process on all CPUs, or a cgroup on all CPUs.
