Difference between UnitResult<T> and Result

[lonix1]

A unit result has no value for the success case, but has an error for the failed case.

How does that differ to using a plain Result?

Result is a shortcut for Result<Unit, string>, whereas UnitResult is a shortcut for Result<Unit, T>. The difference is that in UnitResult the error type may vary, whereas in Result it's set to string. See also this discussion: #321

Was there a real need to introduce UnitResult vs just a struct named Unit ?
Function that has no result could just return Result<Unit, TE> and we could avoid a huge explosion of functions to support UnitResult

I agree. I'm not sure if there was a 100% need for that, the topic itself is arguable. But in my projects, I just use Result<Unit, T>.
