set

open operator fun <A> TArray<A>.set(i: Int, a: A)

Set a variable in the TArray.

import arrow.fx.stm.TArray
import arrow.fx.stm.atomically

suspend fun main() {
//sampleStart
val tarr = TArray.new(size = 10, 2)
val result = atomically {
tarr[5] = 3

tarr[5]
}
//sampleEnd
println("Result $result")
}

Throws if i is out of bounds.

This function never retries.


open operator fun <K, V> TMap<K, V>.set(k: K, v: V)

Alias for STM.insert

import arrow.fx.stm.TMap
import arrow.fx.stm.atomically

suspend fun main() {
//sampleStart
val tmap = TMap.new<Int, String>()
atomically {
tmap[1] = "Hello"
}
//sampleEnd
}
