Pool.State

Mutable runtime state maintained by a Pool.

When to use

Use when you need to inspect or support the runtime state backing a Pool, including its scope, item sets, semaphores, waiters, invalidation tracking, and shutdown flag.

Details

This state tracks the pool scope, active and available items, invalidated items, semaphores, waiters, and shutdown status. It is exposed for inspection and implementation support; user code should prefer the high-level pool operations.

See

• Pool for the pool value exposing this state
• PoolItem for the entries stored in the runtime item sets
• get for acquiring items through the high-level API
• invalidate for invalidating items through the high-level API

Signature

  readonly items: Set<PoolItem<A, E>>
  readonly available: Set<PoolItem<A, E>>
