Methods

OrElse<T1, T2>(IAsyncExecutor<T1, Optional<T2>>, IAsyncExecutable<T1, T2>)

Supplies an asynchronous fallback executable when the source executor produces no value.

[Pure]
public static IAsyncExecutor<T1, T2> OrElse<T1, T2>(this IAsyncExecutor<T1, Optional<T2>> executor, IAsyncExecutable<T1, T2> fallback)

Parameters

executor IAsyncExecutor<T1, Optional<T2>>

fallback IAsyncExecutable<T1, T2>

Fallback asynchronous executable.

Returns

IAsyncExecutor<T1, T2>

Asynchronous executor producing either the original value or the fallback result.

Type Parameters

T1

T2

Exceptions

ArgumentNullException

fallback is null.

OrWhen<T>(IAsyncExecutor<Unit, Optional<T>>, Func<bool>, IAsyncExecutable<Unit, T>)

Adds a parameterless asynchronous conditional fallback executed with an asynchronous executable when the source executor produces no value.

[Pure]
public static IAsyncExecutor<Unit, Optional<T>> OrWhen<T>(this IAsyncExecutor<Unit, Optional<T>> executor, Func<bool> condition, IAsyncExecutable<Unit, T> executable)

Parameters

executor IAsyncExecutor<Unit, Optional<T>>
