PragmaResult #

sealed class PragmaResult<out TSuccess, out TFailure>

A discriminated union that encapsulates a successful outcome with a value of type TSuccess or a failure with of type TFailure. Similar to kotlin.Result, but with non-exception failures.

Constructors #

PragmaResult	`protected fun PragmaResult()`

Functions #

Name	Summary
failureOrNull	`fun failureOrNull(): TFailure?` Returns the held value if this is a failure, or null if not.
fold	`inline fun <TFoldResult> fold(onSuccess: (TSuccess) -> TFoldResult, onFailure: (TFailure) -> TFoldResult): TFoldResult` Returns the result of onSuccess for the encapsulated value if this instance represents success or the result of onFailure function for the encapsulated TFailure if it is failure.
getOrNull	`fun getOrNull(): TSuccess?` Returns the held value if this is a success, or null if not.
getOrThrow	`fun getOrThrow(): TSuccess` Returns the held value if this is a success, or throws an IllegalStateException if not.
onFailure	`fun onFailure(action: (TFailure) -> Unit): PragmaResult<TSuccess, TFailure>` Performs the given action on the encapsulated value if this instance represents failure. Returns the original PragmaResult unchanged.
onSuccess	`inline fun onSuccess(action: (TSuccess) -> Unit): PragmaResult<TSuccess, TFailure>` Performs the given action on the encapsulated value if this instance represents success. Returns the original PragmaResult unchanged.

Extensions #

Name	Summary
andThen	`inline fun <TNewSuccess, TNewFailure, TSuccess, TFailure : TNewFailure> PragmaResult<TSuccess, TFailure>.andThen(onSuccess: (TSuccess) -> PragmaResult<TNewSuccess, TNewFailure>): PragmaResult<TNewSuccess, TNewFailure>` Returns the result of the given onSuccess function applied to the encapsulated TSuccess if this instance represents success or the original encapsulated value if it is failure.
failureOrElse	`inline fun <TNewFailure, TSuccess, TFailure : TNewFailure> PragmaResult<TSuccess, TFailure>.failureOrElse(onFailure: (TSuccess) -> TFailure): TFailure` Returns the encapsulated value if this instance represents failure or the result of onFailure function for the encapsulated TSuccess if it is success.
getOrDefault	`inline fun <TSuccess, TFailure> PragmaResult<TSuccess, TFailure>.getOrDefault(onFailure: () -> TSuccess): TSuccess` Returns the encapsulated value if this instance represents success or the result of if it is failure.
getOrElse	`inline fun <TNewSuccess, TSuccess : TNewSuccess, TFailure> PragmaResult<TSuccess, TFailure>.getOrElse(onFailure: (TFailure) -> TSuccess): TSuccess` Returns the encapsulated value if this instance represents success or the result of onFailure function for the encapsulated TFailure if it is failure.
map	`inline fun <TNewSuccess, TSuccess, TNewFailure, TFailure : TNewFailure> PragmaResult<TSuccess, TFailure>.map(transform: (TSuccess) -> TNewSuccess): PragmaResult<TNewSuccess, TNewFailure>` Returns the result of the given transform function applied to the encapsulated value if this instance represents success or the original encapsulated TFailure value if it is failure.
orElse	`inline fun <TNewSuccess, TNewFailure, TSuccess : TNewSuccess, TFailure> PragmaResult<TSuccess, TFailure>.orElse(onFailure: (TFailure) -> PragmaResult<TNewSuccess, TNewFailure>): PragmaResult<TNewSuccess, TNewFailure>` Returns the result of the given onFailure function applied to the encapsulated TFailure if this instance represents failure or the original encapsulated value if it is success.
recover	`inline fun <TNewSuccess, TSuccess : TNewSuccess, TFailure> PragmaResult<TSuccess, TFailure>.recover(transform: (TFailure) -> TNewSuccess): TNewSuccess` Returns the result of the given transform function applied to the encapsulated TFailure if this instance represents failure or the original encapsulated value if it is success.
