Implementation of the Either and Try types for Java 8+ based on the
Scala Either
and Try types.
Either is a type that represents a value of 1 of 2 possible types (disjoint union). An instance
of Either is an instance of either Left or Right.
Conventionally, Either is used as a replacement for Optional: instead of having an empty
Optional, a Left that contains useful information is used, while Right contains the successful
result.
While Either is right-biased, it is possible to operate on the left values by using a
LeftProjection, obtained by invoking the Either#left() method.
The Try type represents a computation that may either result in an exception, or return a
successfully computed value. It’s similar to, but semantically different from the Either type.
Instances of Try, are either an instance of either Success or Failure.
