Enum postgres_types::Date
source · pub enum Date<T> {
PosInfinity,
NegInfinity,
Value(T),
}
Expand description
A wrapper that can be used to represent infinity with Type::Date
types.
Variants§
PosInfinity
Represents infinity
, a date that is later than all other dates.
NegInfinity
Represents -infinity
, a date that is earlier than all other dates.
Value(T)
The wrapped date.
