mapCatching

Returns the encapsulated result of the given transform function applied to the encapsulated value if this instance represents success or the original encapsulated Throwable exception if it is failure.

inline fun <R, T> Result<T>.mapCatching(transform: (value: T) -> R): Result<R>(source)

fun divide(a: Int, b: Int): Result<Int> =
    try {
        Result.success(a / b)
    } catch (e: Exception) {
        Result.failure(e)
    }

fun main() {
    val successResult = divide(10, 2).mapCatching { it * 2 }
    val failureResult = divide(10, 0).mapCatching { it * 2 }

    println(successResult)  // Result.success(10)
    println(failureResult)  // Result.failure(java.lang.ArithmeticException: / by zero)
}
