## pool

**pool** is a Scala port of Bryan O'Sullivan's excellent Haskell resource-pooling library [bos/pool](https://github.com/bos/pool).

**pool** makes extensive use of the facilities provided by the [Monix](https://monix.io/) library.

### Example

```scala

implicit val scheduler = Scheduler.io(

  name = "pool-test",

  reporter = UncaughtExceptionReporter(

    logger.error(s"pool-test: Uncaught exception in IO scheduler", _)))

// Run a `Pool[Unit] => Task[Unit]`

val usePool = Pool.withPool[Unit, Unit](

  name = "test",

  create = Task.eval(logger.info("Creating entry")),

  destroy = a => Task.eval(logger.info(s"Destroying entry $a")),

  minIdle = 5,

  maxEntries = 10,

  idleTimeout = 60.seconds,

  creatorDelay = 1.second,

  creatorInterval = 1.second,

  reaperDelay = 1.second,

  reaperInterval = 1.second

) { pool =>

    pool.withResource(a => Task.fork(Task.eval(Thread.sleep(5000))))

  }

Await.result(usePool.runAsync, Duration.Inf)

```
