Success

data class Success<Error, Value>(data: Value) : Result<Error, Value>

A successful result of a computation.

Parameters

data

the value returned by the computation.

Constructors

Success

fun <Value> Success(data: Value)

the value returned by the computation.

Functions

andThen

fun <T> andThen(chain: (Value) -> Result<Error, T>): Result<Error, T>

Chain two computations togetherIf in a computation chain the result of one computation is needed as input for another computation, andThen is there to chain the computations together.

andThenError

fun <T> andThenError(chain: (Error) -> Result<T, Value>): Result<T, Value>

Chain two computations together for error recovery.

component1

operator fun component1(): Value

copy

fun copy(data: Value): Success<Error, Value>

equals

map

fun <T> map(transform: (Value) -> T): Result<Error, T>

Transform a successful result.

mapError

fun <T> mapError(transform: (Error) -> T): Result<T, Value>

Transform a failed result.

orThrowException

fun orThrowException(exceptionProducer: (Error) -> Exception): Value

Unwrap the result by throwing an Exception that can depend on the kind of failureif a computation was a Success, return that data.
