Struct BitsArray

pub struct BitsArray<'a, const N: usize> { /* private fields */ }

This struct wraps a provided borrowed static array in a MutBits impl. Operates like a slice, walking through the array filling it up.

Implementations

impl<'a, const N: usize> BitsArray<'a, N>

pub fn new(arr: &'a [u8; N]) -> Self

A new view into the backed array, limited only by the length of the backed array

pub fn new_limited(arr: &'a [u8; N], max_len: usize) -> Self

A new view into the backed array, limited by the provided maximum length.

pub fn reset(&mut self)

Resets the reading position back to the start of the array.
