Say, we have a bit vector ---

it's nothing better than a Vec<bool>, but ...

what if we implement it,

and save some poor bits of memory?

Quick Start

use bitvek::bitvec;

let vec = bitvec![
    true, true, true, true, false, false, false, false,
    false, false, false, false, true, true, true, true,
];

Find it cumbersome? Try this:

#
// requires the total number of bits to be a multiple of 8
let vec = bitvec![0b11110000, 0b00001111];

Memory Efficiency

To achieve memory savings, the total number of bits stored must exceed twice the machine word size in bytes, corresponding to 8 for 32-bit systems and 16 for 64-bit systems.
