Function postgis_diesel::operators::overlaps_or_above

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

The |&> operator returns TRUE if the bounding box of geometry A overlaps or is above the bounding box of geometry B, or more accurately, overlaps or is NOT below the bounding box of geometry B.
