Kds is a Data Structure library for Multiplatform Kotlin.
It includes a set of optimized data structures written in Kotlin Common so they are available in
JVM, JS and future multiplatform targets. Those structures are designed to be allocation-efficient and fast, so Kds
include specialized versions for primitives like Int
or Double
.

// Case Insensitive Map
val map = mapOf("hELLo" to 1, "World" to 2).toCaseInsensitiveMap()
println(map["hello"])
// BitSet
val array = BitSet(100) // Stores 100 bits
array[99] = true
// TypedArrayList
val v20 = intArrayListOf(10, 20).getCyclic(-1)
// Deque
val deque = IntDeque().apply {
addFirst(n)
removeFirst()
addLast(n)
}
// CacheMap
val cache = CacheMap<String, Int>(maxSize = 2).apply {
this["a"] = 1
this["b"] = 2
this["c"] = 3
assertEquals("{b=2, c=3}", this.toString())
}
// IntIntMap
val m = IntIntMap().apply {
this[0] = 98
}
// Pool
val pool = Pool { Demo() }
pool.alloc { demo ->
println("Temporarilly allocated $demo")
}
// Priority Queue
val pq = IntPriorityQueue()
pq.add(10)
pq.add(5)
pq.add(15)
assertEquals(5, pq.removeHead())
// Extra Properties
class Demo : Extra by Extra.Mixin() { val default = 9 }
var Demo.demo by Extra.Property { 0 }
var Demo.demo2 by Extra.PropertyThis<Demo, Int> { default }
val demo = Demo()
assertEquals(0, demo.demo)
assertEquals(9, demo.demo2)
demo.demo = 7
assertEquals(7, demo.demo)
assertEquals("{demo=7, demo2=9}", demo.extra.toString())
// mapWhile
val iterator = listOf(1, 2, 3).iterator()
assertEquals(listOf(1, 2, 3), mapWhile({ iterator.hasNext() }) { iterator.next()})
// And much more!
