Struct bv::adapter::BoolAdapter

[+] Show declaration

pub struct BoolAdapter<Block, T> { /* fields omitted */ }

[−] Expand description

Adapts a sequence of bools (e.g., &[bool]) to emulate a bit vector.

In particular, this adapter implements Bits, BitsMut, and BitsPush as appropriate. It implement PartialEq<T> for all T: Bits<Block=Block>. It does not, however, implement slicing, so slice before you adapt.

Note that a bare Vec<bool> or &[bool] already implements Bits, etc., with a Block type of u8. This means that it is only compatible with other u8-based bit vectors. BoolAdapter is instead parametrized by the block type, so it works with bit vectors, slices, and adapters of any uniform block type.

Implementations

impl<Block: BlockType, T> BoolAdapter<Block, T>[−]

pub fn new(bits: T) -> Self[−]

Creates a new BoolAdapter from an underlying sequence of bools.

Note that the BoolAdapter derefs to the underlying bool sequence.

Examples

use bv::BitSliceable;
use bv::adapter::BoolAdapter;

let array = [0b101usize];
let bv1 = BoolAdapter::new(vec![true, false, true]);
let bv2 = array.bit_slice(0..3);
assert_eq!( bv1, bv2 );

pub fn into_inner(self) -> T[−]

Gets the underlying bool sequence object back out of a BoolAdapter.
