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() {
//sampleStart
val tq = TQueue.new<Int>()
val result = atomically {
tq.size()
}
//sampleEnd
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.
