TST: Series repr with pyarrow date32 type by mroeschke · Pull Request #48258 · pandas-dev/pandas (original) (raw)

@jbrockmendel don't know if you've ever hit this while working on EA.argmin/max/sort. For some reason (seemly) unrelated type's, in this case timedelta, argmin/max/sort fail. I got a similar error when trying to define ArrowExtensionArray._values_for_argsort, but ended up removing it since I just could define ArrowExtensionArray.argmin/max/sort instead.
