:datetime with constraints vs :utc_datetime_usec

Hey all, I’m looking at the docs for the different datetime options and they mention >A wrapper around :datetime for backwards compatibility https://hexdocs.pm/ash/Ash.Type.UtcDatetimeUsec.html In a new project with the latest version of Ash what is the most appropriate way to define a timestamp with microsecond precision? Should I prefer:

attribute :xx, :datetime do
  constraints precision: microsecond
end

attribute :xx, :datetime do
  constraints precision: microsecond
end

attribute :xx, :utc_datetime_usec

attribute :xx, :utc_datetime_usec

I don’t quite understand what the implication of the “warning” about backward compatibility is :/

Solution:

They are equivalent and will likely not change anytime soon. Someday we may warn when you use :utc_datetime_usec over the constraint.
