Struct NibbleVec

impl<A: Array<Item = u8>> NibbleVec<A>

fn new() -> NibbleVec<A>

Create an empty nibble vector.

fn from_byte_vec(vec: Vec<u8>) -> NibbleVec<A>

Create a nibble vector from a vector of bytes.

Each byte is split into two 4-bit entries (MSB, LSB).

fn as_bytes(&self) -> &[u8]

Returns a byte slice of the nibble vector's contents.

fn into_bytes(self) -> Vec<u8>

Converts a nibble vector into a byte vector.

This consumes the nibble vector, so we do not need to copy its contents.

fn len(&self) -> usize

Get the number of elements stored in the vector.

fn is_empty(&self) -> bool

Returns true if the nibble vector has a length of 0.

fn get(&self, idx: usize) -> u8

Fetch a single entry from the vector.

Guaranteed to be a value in the interval [0, 15].

Panics if idx >= self.len().

fn push(&mut self, val: u8)

Add a single nibble to the vector.

Only the 4 least-significant bits of the value are used.

fn split(&mut self, idx: usize) -> NibbleVec<A>

Split the vector into two parts.

All elements at or following the given index are returned in a new NibbleVec, with exactly idx elements remaining in this vector.

Panics if idx > self.len().

fn join(self, other: &NibbleVec<A>) -> NibbleVec<A>

Append another nibble vector whilst consuming this vector.
