Struct SchedSample 

pub struct SchedSample {
    pub nr_switches: u64,
    pub sum_exec_runtime_ns: u64,
    pub captured_at: Instant,
}

Snapshot of the two scheduler counters this monitor watches.

Mirrors what kernel/sched/debug.c::proc_sched_show_task writes to /proc/<pid>/sched. Both fields are cumulative since task creation; the monitor tracks deltas between consecutive samples rather than absolute values.

Fields

nr_switches: u64

nr_switches from /proc/<pid>/sched — total voluntary + involuntary context switches involving this task.

sum_exec_runtime_ns: u64

sum_exec_runtime from /proc/<pid>/sched — cumulative on-CPU runtime in nanoseconds.

captured_at: Instant

Instant the sample was captured. Stored alongside the counters so a downstream consumer can compute wall-clock deltas without re-deriving the poll cadence. Not serialized — Instant is a monotonic-clock opaque value with no portable wire form; serde consumers reading a sidecar dump will see Instant::now() as the default. The wall-clock context for the report is carried separately by StallReport::captured_at (also #[serde(skip)] for the same reason; sidecar dump consumers anchoring across runs should pair the report with the run’s start timestamp from elsewhere).

Trait Implementations

impl Clone for SchedSample

fn clone(&self) -> SchedSample

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SchedSample

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SchedSample

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SchedSample

fn eq(&self, other: &SchedSample) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SchedSample

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
