const program = Effect.gen(function*() {
  const pq = yield* TxPriorityQueue.fromIterable(Order.Number, [1, 2, 3, 4, 5])
  yield* TxPriorityQueue.retainIf(pq, (n) => n % 2 === 0)
  const all = yield* TxPriorityQueue.takeAll(pq)
  console.log(all) // [2, 4]
})

Signature

declare const retainIf: { <A>(predicate: Predicate<A>): (self: TxPriorityQueue<A>) => Effect.Effect<void>; <A>(self: TxPriorityQueue<A>, predicate: Predicate<A>): Effect.Effect<void>; }
