Enum perf_event_data::SwitchCpuWide

pub enum SwitchCpuWide {
    In {
        pid: u32,
        tid: u32,
    },
    Out {
        pid: u32,
        tid: u32,
    },
}

SWITCH_CPU_WIDE records indicates a context switch when profiling in cpu-wide mode.

It provides some additional info on the process being switched that is not provided by SWITCH.

If the PERF_RECORD_MISC_SWITCH_OUT bit is set within the record header then it was a context switch away from the current process, otherwise it is a context switch into the current process.

This enum corresponds to PERF_RECORD_SWITCH_CPU_WIDE. See the manpage for more documentation.
