PoolItem

PreviousNext

API reference for PoolItem.

One acquisition: its exit, its finalizer, and how it is used.

ref_count counts the leases on it, reservations the reserve calls holding it out of circulation. idle_since is the pool clock's wall time, in whole nanoseconds, when its last lease returned (or when it was acquired).
