Struct BitVec 

pub struct BitVec { /* private fields */ }

Minimal bit-vector. Backing storage is Vec<u64> words.

We expose only the operations the atom-selection layer needs: construction, get, set, count_ones, and iteration of set indices. This is deliberately tiny — adding the external bitvec crate would be overkill for a few hundred bits per observation.

Implementations

impl BitVec

pub fn zeros(len: usize) -> Self

All-zero bitset of length len.

pub fn ones(len: usize) -> Self

All-ones bitset of length len.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&self, i: usize) -> bool

pub fn set(&mut self, i: usize, v: bool)

pub fn count_ones(&self) -> usize

Number of set bits.

pub fn iter_ones(&self) -> impl Iterator<Item = usize> + '_

Iterator over set indices in ascending order.

pub fn clear(&mut self)

Zero all bits in place.

Trait Implementations

impl Clone for BitVec

fn clone(&self) -> BitVec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BitVec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for BitVec

impl PartialEq for BitVec

fn eq(&self, other: &BitVec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
