Function postgis_diesel::operators::g_same

pub fn g_same<T, U>(left: T, right: U) -> GSame<T, U::Expression>where
    T: Expression,
    <T as Expression>::SqlType: SqlType,
    U: AsExpression<T::SqlType>,

The = operator returns TRUE if the coordinates and coordinate order geometry/geography A are the same as the coordinates and coordinate order of geometry/geography B.
