interface TxPriorityQueue<in out A>A transactional priority queue backed by a sorted Chunk.
Details
Elements are stored in ascending order according to the Order provided at
construction time. take returns the smallest element, peek observes it
without removing.
Example (Dequeuing values by priority)
import { Effect, Order, TxPriorityQueue } from "effect"
const program = Effect.gen(function*() {
const pq = yield* TxPriorityQueue.empty<number>(Order.Number)
yield* TxPriorityQueue.offer(pq, 3)
yield* TxPriorityQueue.offer(pq, 1)
yield* TxPriorityQueue.offer(pq, 2)
const first = yield* TxPriorityQueue.take(pq)
console.log(first) // 1
})

) => Effect.Effect<A>
Reads the current value of the TxRef.
When to use
Use to read the current value of a TxRef.
Example (Reading transactional references)
import { Effect, TxRef } from "effect"
const program = Effect.gen(function*() {
const counter = yield* TxRef.make(42)
// Read the value within a transaction
const value = yield* Effect.tx(
TxRef.get(counter)
)
console.log(value) // 42
})
