Class FutureResult<E,T>

java.lang.Object

io.simplesource.data.FutureResult<E,T>

Type Parameters:

E - on failure there will be a NonEmptyList of error instances with an error value of this type.

T - when successful there will be a contained value of this type.

public final class FutureResult<E,T>
extends Object

Represents an operation that calculates an Result asynchronously.
