Partial Functions to Functions
Functions that are not defined for every input are known as partial functions.
Below is the Scala program to transform a partial function into a function:
// Define a partial function
val divide: PartialFunction[(Int, Int), Int] = {
case (x, y) if y != 0 => x / y
}
// Convert partial function to a total function
val divideTotal: ((Int, Int)) => Option[Int] = divide.lift
// Test the total function
println(divideTotal(10, 2))
println(divideTotal(10, 0))
Output:

What is Lifting in Scala?
Scala is a programming language that is expressive and effective. It permits builders to produce code that is both elegant and succinct. Lifting is one such belonging that is vital to useful programming paradigms. Functions may fit easily on values interior containers, such as Option, List, Future, and many others., thanks to lifting, which gets rid of the need to manage the structure of the container manually. This article will explain the idea of lifting in Scala, spotlight its importance, and provide utilization examples.
