common open fun <A> TQueue<A>.size(): Int

Return the current number of elements in a TQueue

import arrow.fx.stm.TQueue
import arrow.fx.stm.atomically

suspend fun main() {
  val tq = TQueue.new<Int>()
  val result = atomically {
  println("Result $result")

This function never retries.

This function has to access both [TVar](../-t-var/index.html)'s and thus may lead to increased contention, use sparingly.
