Package Multiple Result

The reason I use this package is that its implementation is very small with a good amount of tests. With this package, we get a couple of new types/objects that we can use.

Result - Failure | OurOtherType

With Result<Failure, OurOtherType, we specify that our type can be either a Failure or the specific type we use in the code. This lets us return a value if we are successful with the try clause or return a failure in the catch clause. When we later call this we have to handle it which makes the implementation needed in the controller minimal.

Success

This is the object we wrap the value we wanted to return to our controller and of course should represent the value of the successful data we got back.

Error

This is the object we wrap our custom failure object with. This will be handled in the controller the same way as the success object.

.when()

This is the method we use on our returned results from the Service. This will force us to handle both the success and the failure cases. In our controller, it becomes very easy to understand and read.
