You probably noticed that .SetName() returns a Either. You may have come across Unit in libraries like MediatR or Language-Ext. It's a simple construct representing a type with only one possible value. We use it as a placeholder for operations that do not return a value but may return another state. In our example, .SetName() is a Command that does not return a value but may fail. Therefore, the monad Either carries two possible states: Right (without value) or Left (with an Error).
Hey, I am considering adopting the Result pattern in my codebase. Wanted to get some opinions from someone who has experience with it: should I start with language-ext or FunctionalExtensions?
Since then C# introduced nullable which takes away some of the needs for a Option type. So what is your opionion? Do libraries like Optional still have a place when nullable is enabled?
Project mention: Rolled my own Result<T,E> type that seems to work better than others. | /r/csharp | 2023-11-01BUT It is possible to implement it in a pretty good way. The main issue with the majority of existing libraries is that they're not able to guarantee that Error variant matching is exhaustive. Thus I'd recommend the usage of code generators libraries (https://github.com/domn1995/dunet looks like a good choice to start with) to build Result and Error(s) unions in a proper way
