Struct ThreadPoolStats 

pub struct ThreadPoolStats {
    pub lifecycle: ExecutorServiceLifecycle,
    pub core_pool_size: usize,
    pub maximum_pool_size: usize,
    pub live_workers: usize,
    pub idle_workers: usize,
    pub queued_tasks: usize,
    pub running_tasks: usize,
    pub submitted_tasks: usize,
    pub completed_tasks: usize,
    pub cancelled_tasks: usize,
    pub terminated: bool,
}

Point-in-time counters reported by crate::ThreadPool.

The snapshot is intended for monitoring and tests. It is not a stable synchronization primitive; concurrent submissions and completions may make the next snapshot different immediately after this one is returned.

Fields

lifecycle: ExecutorServiceLifecycle

Observed lifecycle state.

core_pool_size: usize

Configured core pool size.

maximum_pool_size: usize

Configured maximum pool size.

live_workers: usize

Number of live worker loops.

idle_workers: usize

Number of workers currently waiting for work.

queued_tasks: usize

Number of queued tasks waiting for a worker.

running_tasks: usize

Number of tasks currently held by workers.

submitted_tasks: usize

Number of tasks accepted since pool creation.

completed_tasks: usize

Number of accepted jobs completed or otherwise made inactive without queued cancellation.

cancelled_tasks: usize

Number of queued jobs cancelled by immediate shutdown.

terminated: bool

Whether the pool has fully terminated.

Trait Implementations

impl Clone for ThreadPoolStats

fn clone(&self) -> ThreadPoolStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadPoolStats

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

Formats the value using the given formatter.

impl Default for ThreadPoolStats

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ThreadPoolStats

fn eq(&self, other: &ThreadPoolStats) -> 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 Copy for ThreadPoolStats
