Looking at the Either crate api, it’s awful. At least Result gives you a meaningful name for each variant (ok, err).
Either gives you a... left and a right. Which is which? If both have the same content type, how do you differentiate?
By the way, some people (like me) can’t tell the right from the left. Or rather can’t give them a name (but never will for example drive on the wrong side of the road). I had to work on codd which used an Either type in another language and could never manage to understand any of it even after multiple years.
I guess it’self OK as write-only code...

Agree. Having worked with either in scala I can say that the overhead of a dedicated struct/union/variant is minimal - and the readability is much higher! This is the wrong place to be lazy.
