此crate提供了BoolVec结构。这基本上是一个围绕Vec<u8>的包装，其中每个字节都被解释为8个bool。

快速提示：对这段代码做你想做的，我实际上并不在乎 :)

示例

// Create a new `BoolVec`
use boolvec::BoolVec;

let mut vec = BoolVec::new();

// You can push data onto it
vec.push(true);
vec.push(false);

// ... retreve it
assert_eq!(vec.get(0), Some(true));
assert_eq!(vec.get(3), None);

// ... update it
vec.set(0, false);
assert_eq!(vec.get(0), Some(false));

// You can get a reference to an unaligned boolean.
let mut boolean = vec.get_mut(1).unwrap();
assert_eq!(boolean.get(), false);

boolean.set(true);
assert_eq!(vec.get(1), Some(true));

// You can also iterate over this data (mutably or not).
let mut iter = vec.iter_mut();

iter.next().unwrap().set(true);
iter.next().unwrap().set(false);

let mut iter = vec.iter();

assert_eq!(iter.next(), Some(true));
assert_eq!(iter.next(), Some(false));
assert_eq!(iter.next(), None);
