Scala Things To Know

Question 1

implicit

Answer 1

Used to tell compiler to look for a specific type -> and if that type is not found, to look for a function that will convert the found type into the desired type.

Ex. To convert a value to an int we could do the following without use of implicits:

def doubleToInt(x: Double): Int = x.toInt
val x: Int = doubleToInt(42.0)

—OR WITH IMPLICIT—

implicit def doubleToInt(d: Double) = d.toInt
val x: Int = 42.0 //auto-converts this to an Int
