Encode an index of a nibble from a u64 as a u8.
| 4 bits | 4 bits |
| index of nibble | nibble of data |
Usage
use crumb::Crumb;
fn main() {
let crumb = Crumb::new(1, 0b11111111).unwrap();
// bits outside of the index are discarded
assert_eq!(0b11110000u64, crumb.get_u64());
}Name
A nibble of something is about the size of a crumb or something like that…
Why?
Was doing some research on variable length integers and realized how nicely this fits.
For What?
Not sure!
I don’t think there are too many applications for this.
