Struct PoolMetrics 

#[non_exhaustive]
pub struct PoolMetrics {
    pub thread_limit: usize,
    pub threads: usize,
    pub active_tasks: usize,
    pub queue_depth: usize,
    pub tasks: u64,
    pub wait_duration: Duration,
    pub busy_duration: Duration,
}

Snapshot of ThreadPool metrics.

Durations and task counts are totals since the pool was created. Rates and averages over an interval are computed from the deltas of two snapshots, e.g. the average queue wait is the wait_duration delta divided by the tasks delta.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

thread_limit: usize

Maximum number of worker threads.

threads: usize

Number of worker threads, busy or idle.

active_tasks: usize

Number of tasks being executed.

queue_depth: usize

Number of tasks waiting for a worker thread.

tasks: u64

Number of tasks started.

wait_duration: Duration

Total time started tasks waited for a worker thread.

busy_duration: Duration

Total time worker threads spent executing tasks.
