Function morton_encoding::bloat_custom_checked [−][src]
pub fn bloat_custom_checked<Coor, Key>(
x: Coor,
siz_rat: NonZeroUsize
) -> Option<Key> where
Coor: ToPrimitive,
Key: ValidKey<Coor>,
Fallibly “bloats” a given number, interleaving its bits with zeroes.
Returns an Option
.
Each input bit is interleaved with siz_rat - 1
zeroes.
Alternatively, if the provided Key
type is too small to
fit siz_rat
Coor
numbers inside it, a None
is returned.
This function is usable when the size ratio is computed at run-time, but bear in mind that it might run much more slowly than its compile-time counterparts.
Examples
assert_eq!(bloat_custom_checked(0xFFFFu16, nz(2)), Some(0x55555555u32)); assert_eq!(bloat_custom_checked::<u16, u32>(0xFFFF, nz(3)), None);
