Struct WarmPoolMetrics 

pub struct WarmPoolMetrics {
    pub created_total: u64,
    pub acquired_total: u64,
    pub evicted_total: u64,
    pub refill_runs_total: u64,
    pub validation_failures_total: u64,
}

Snapshot of counters intended for Prometheus-style scraping. Cloned cheaply via WarmPool::metrics; no metrics library dependency by design.

Fields

created_total: u64

Total number of pool entries ever spawned (refill thread).

acquired_total: u64

Total number of successful acquires.

evicted_total: u64

Total number of entries evicted (age, validation failure, shutdown).

refill_runs_total: u64

Total number of refill scheduler ticks the thread has executed.

validation_failures_total: u64

Total number of acquires that drained an unhealthy entry before returning. Indicates pool quality, not pool throughput.
