Crate quartet

quartet provides useful abstractions for working with data that is described/structure in 4-bit chunks.

Examples

use quartet::NibSlice;
let nib_slice = NibSlice::from_bytes_skip_last(&[0x12, 0x34, 0x50]);
println!("{}", nib_slice); // "12345"
assert_eq!(format!("{}", nib_slice), "12345");
assert_eq!(nib_slice.index(1), 2);

use quartet::NibSlice;
let ns = NibSlice::from_bytes_exclude(&[0x12, 0x34, 0x56], quartet::Exclude::Both);
assert_eq!(ns, NibSlice::from_bytes(&[0x23, 0x45]));

let sns = ns.index(1..);
assert_eq!(sns, NibSlice::from_bytes_skip_last(&[0x34, 0x50]));

Structs

Iter	Iterate over a NibSlice, returning a nibble for each item
NibSlice	A const slice (&[u4]) over nibbles (4-bit values)

Enums

Exclude

Which nibbles are excluded from the NibSlice but are included in the internal [u8]

Traits

SliceIndex

A helper trait used for indexing operations

Functions

decompose_offset

Decompose a nibble offset into byte oriented terms.
