BUT 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
