recoverCatching

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

inline fun <R, T : R> Result<T>.recoverCatching(transform: (exception: Throwable) -> R): Result<R>(source)

import kotlin.runCatching

fun main() {
    // Successful parsing
    val success = runCatching { "42".toInt() }                 // Result<Int>
    val recoveredSuccess = success.recoverCatching { e -> 0 }   // Result<Number>
    println(recoveredSuccess.getOrThrow()) // prints 42

    // Failed parsing, recover to a default value
    val failure = runCatching { "not a number".toInt() }       // Result<Int>
    val recoveredFailure = failure.recoverCatching { e -> 0 }  // Result<Number>
    println(recoveredFailure.getOrThrow()) // prints 0
}
