Struct SchedulerTickCpuTime 

pub struct SchedulerTickCpuTime { /* private fields */ }

IRQ-safe tick-sampled user/system CPU time for one scheduler thread.

The object is retained by both the OS task and super::ThreadExtension. Only the current CPU samples it from the periodic tick’s saved trap origin.

Implementations

impl SchedulerTickCpuTime

pub const fn new() -> Self

Creates an empty accounting stream.

pub fn with_realtime_gate(gate: Arc<SchedulerTickGate>) -> Self

Creates tick accounting with optional continuous real-time accounting.

The OS owns the shared gate. While enabled, actual FIFO/RR class ticks count at most once per common monotonic-clock period, including across migration. A real-time wake or PI deboost to Fair resets the count but preserves deduplication. Disabling the gate preserves previously accumulated ticks.

pub fn realtime_ticks(&self) -> Option<(u64, NonZeroU64)>

Returns continuous real-time ticks and their fixed period in nanoseconds.

Returns None until the first enabled real-time tick, or when this stream has no real-time accounting. The period cannot change during the stream’s lifetime. A wake or PI deboost may concurrently reset the count.

pub fn snapshot(&self) -> SchedulerTickCpuTimeSnapshot

Returns the raw tick-accounted totals.

Trait Implementations

impl Default for SchedulerTickCpuTime

fn default() -> Self

Returns the “default value” for a type.
