Struct TaskStats 

pub struct TaskStats {
    pub id: TaskId,
    pub status: TaskStatus,
    pub priority: Priority,
    pub spawn_time: Instant,
    pub start_time: Option<Instant>,
    pub completion_time: Option<Instant>,
    pub cpu_time_ns: u64,
}

Detailed statistics about a specific task.

Task statistics report the lifecycle timing the executor actually tracks: spawn, start, and completion timestamps from a monotonic high-resolution clock, plus the derived execution duration.

Fields

id: TaskId

Task identifier

status: TaskStatus

Current status

priority: Priority

Priority level

spawn_time: Instant

When the task was spawned

start_time: Option<Instant>

When the task started executing (if started)

completion_time: Option<Instant>

When the task completed (if completed)

cpu_time_ns: u64

Total CPU time used (nanoseconds), derived from the lifecycle start/completion timestamps.

Implementations

impl TaskStats

pub fn execution_time(&self) -> Option<Duration>

Returns the total execution time of the task, if available.

Returns

Some(duration) if the task has completed execution, None if still running or queued.

pub fn queue_time(&self) -> Option<Duration>

Returns the time the task spent in the queue before execution.

Returns

• Some(duration_since_spawn) if task is still queued
• Some(queue_duration) if task has started execution
• None if timing information is unavailable

pub fn is_active(&self) -> bool

Returns whether the task is currently active (queued or running).

pub fn is_finished(&self) -> bool

Returns whether the task has reached a terminal state.

Trait Implementations

impl Clone for TaskStats

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskStats

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

Formats the value using the given formatter.
