This PR adds the covariant annotation
+
on the type parameter of the alias used in e.g.ParseResult
, as the aliased type is using this parameter in the covariant position.This should not cause any changes in the library, however, fixes an issue with using typeclasses from zio-prelude, which use variance annotations.
I also added it on the
CvsReader
alias, becauseResourceIterator
is also covariant, though technically I didn't have to for this PR.
