Function morton_encode_generic 

pub fn morton_encode_generic<Coor, Key, Coors>(coors: Coors) -> Key
where
    Coor: ToPrimitive,
    Key: ValidKey<Coor>,
    Coors: IntoIterator<Item = Coor>,
    <Coors as IntoIterator>::IntoIter: ExactSizeIterator,

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

Meant to be used with statically-known iterator lengths. If that is not the case, the checked version of this function (morton_encode_checked) should be used instead.

Panics

This function will panic if the Key value provided does not have enough length for all the values in the iterator.

In the future, we would like to constrain it for iterators that have exactly const N elements, but that’s still quite far away.

Examples

let input = vec!(0u8, 255);
let result: u16 = morton_encode_generic(input);
assert_eq!(result, 0x5555);

In the event that one Key is strictly larger than all Coors put together, all significant bits are gathered at the end, and extraneous bits at the beginning are cleared. The following example illustrates the difference:

let input = vec!(255u8; 3);
let result: u32 = morton_encode_generic(input);
assert_eq!(result, 0b_0000_0000_111_111_111_111_111_111_111_111u32);
let input = vec!(0u8, 255, 255, 255);
let result: u32 = morton_encode_generic(input);
assert_eq!(result, 0b_0111_0111_0111_0111_0111_0111_0111_0111u32);
