Vl-maybe-timeprecisiondecl

Option type; vl-timeprecisiondecl or nil.

This is an option type introduced by defoption. Note that defoption is just a wrapper for defflexsum, so there are :none and :some member types, a case macro, and so forth.

Member Types

:none → vl-maybe-timeprecisiondecl-none

Represents that no vl-maybe-timeprecisiondecl is available, i.e., Nothing or None.

:some → vl-maybe-timeprecisiondecl-some

An available vl-maybe-timeprecisiondecl, i.e., Just val or Some val.
