Struct BitMask 

pub struct BitMask {
    pub bits: Vec<u32>,
    pub len: usize,
    pub count: usize,
}

Fields

bits: Vec<u32>

len: usize

count: usize

Implementations

impl BitMask

pub fn new(len: usize) -> BitMask

Creates a new BitMask initialized to zero.

pub fn full(len: usize) -> BitMask

pub fn set(&mut self, index: usize)

Sets the bit at the given index to 1. No-ops silently if the bit is already set so count stays accurate.

pub fn unset(&mut self, index: usize)

Clears the bit at the given index to 0. No-ops silently if the bit is already clear so count stays accurate.

pub fn is_set(&self, index: &usize) -> bool

Returns true if the bit at the given index is 1.

pub const fn is_empty(&self) -> bool

pub const fn is_full(&self) -> bool

pub fn clear(&mut self)

Clears all bits (resets to zero) without reallocating.

pub fn and(&mut self, other: &BitMask)

Performs a bitwise AND in-place (intersection). Recounts set bits via popcount after the operation.

pub fn or(&mut self, other: &BitMask)

Performs a bitwise OR in-place (union). Recounts set bits via popcount after the operation.

pub fn iter(&self) -> BitMaskIter<'_>

Returns a high-performance iterator over the indices of set bits.

pub fn concat(self, b: BitMask) -> BitMask

pub fn extend(&mut self, b: BitMask)

impl BitMask

pub fn iter_zeros(&self) -> BitMaskZerosIter<'_>

Trait Implementations
