Struct ConnRegistry

Source

pub struct ConnRegistry {
    counters: DashMap<String, Arc<AtomicI64>>,
}

Expand description

Per-key in-flight request counters for limit-conn.

The acquire node increments and the release node decrements the same counter, so concurrency is measured across the whole pipeline between the paired nodes.

Fields§

§counters: DashMap<String, Arc<AtomicI64>>
