A type representing the error state of a Result, containing either
an expected error of type E or an unexpected ResultError.
This type ensures exactly one error is present: either an expected error
(an anticipated failure of type E) or an unexpected error (a runtime or
exceptional failure). Use isExpected or
isUnexpected to narrow the type if needed.
