Enum madsim_tokio_postgres::types::Date

source · [−]

pub enum Date<T> {
    PosInfinity,

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.
