KmmResult

sealed class KmmResult<out T>

For easy use of this KMM library under iOS, we need a class like Result that is not a value class (which is unsupported in Kotlin/Native)

Types

Companion

object Companion

Failure

class Failure : KmmResult<Nothing>

Success

class Success<T> : KmmResult<T>

Functions

exceptionOrNull

inline fun exceptionOrNull(): Throwable?

Returns the encapsulated Throwable exception if this instance represents failure or null if it is success.

fold

inline fun <R> fold(onSuccess: (value: T) -> R, onFailure: (exception: Throwable) -> R): R

Returns the result of onSuccess for the encapsulated value if this instance represents success or the result of onFailure function for the encapsulated Throwable exception if it is failure.

getOrElse

inline fun <R : @UnsafeVariance T> getOrElse(onFailure: (exception: Throwable) -> R): T

Returns the encapsulated value if this instance represents success or the result of onFailure function for the encapsulated Throwable exception if it is failure.

getOrNull

fun getOrNull(): T?

Returns the encapsulated value if this instance represents success or null if it is failure.

getOrThrow

fun getOrThrow(): T

Returns the encapsulated value if this instance represents success or throws the encapsulated Throwable exception if it is failure.

map

inline fun <R : Any> map(block: (T) -> R): KmmResult<R>

Transforms this KmmResult's success-case according to block and leaves the failure case untouched (type erasure FTW!)

mapFailure

inline fun mapFailure(block: (Throwable) -> Throwable): KmmResult<T>

Transforms this KmmResult's failure-case according to block and leaves the success case untouched (type erasure FTW!)

unwrap

inline fun unwrap(): Result<T>

Returns a Result equivalent of this KmmResult
