In programming languages like Kotlin, the Nothing type denotes a type that has no values. This means that a function or expression with the Nothing type never returns normally — for example, it may terminate with an exception or in an infinite loop.
Example of usage:
fun fail(message: String): Nothing {
throw IllegalArgumentException(message)
}
Here, the fail function never returns a value, it always throws an exception. The Nothing type helps the compiler understand that after calling such a function, the code will not continue, which improves code analysis and safety.
