Function morton_encode_generic_checked 

Source 
pub fn morton_encode_generic_checked<Coor, Key, Coors>(
    coors: Coors,
) -> Option<Key>
where
    Coor: ToPrimitive,
    Key: ValidKey<Coor>,
    Coors: IntoIterator<Item = Coor>,
    <Coors as IntoIterator>::IntoIter: ExactSizeIterator,
Expand description

Receives an iterator of Coor values and encodes them all in a Option<Key> value.

Returns a None if the iterator is empty, or if it is too large for all the Coor values contained within to fit inside a Key type.
