Methods

flatMap<T>(Result<T, F> transform(S value)) → Result<T, F>

FlatMap for chaining Result-returning operations

override

flatMapAsync<T>(Future<Result<T, F>> transform(S value)) → Future<Result<T, F>>

Available on Result<S, F>, provided by the ResultAsyncExtensions extension

FlatMap with an async function

fold<T>(T onSuccess(S value), T onFailure(F error)) → T

Fold the result into a single value

override

foldAsync<T>(Future<T> onSuccess(S value), Future<T> onFailure(F error)) → Future<T>

Async version of fold

inherited

getFailureOrNull() → F?

Get the failure value or null

override

getOrElse(S defaultValue()) → S

Get the success value or return a default

override

getOrNull() → S?

Get the success value or null

override

getOrThrow() → S

Get the success value or throw the failure

override

map<T>(T transform(S value)) → Result<T, F>

Map the success value to a new type

override

mapAsync<T>(Future<T> transform(S value)) → Future<Result<T, F>>

Available on Result<S, F>, provided by the ResultAsyncExtensions extension
