Struct BitSet128 

pub struct BitSet128(/* private fields */);

A memory-efficient 128-bit set for embedded environments.

Implementations

impl BitSet128

pub const fn new() -> Self

Create a new empty bitset.

impl BitSet128

pub fn reset_all(&mut self)

Resets all bits to 0.

pub fn reset(&mut self, index: u8)

Resets the bit at index to 0. Does nothing if the index is out of bounds.

pub fn set_all(&mut self)

Sets all bits to 1.

pub fn set(&mut self, index: u8)

Sets the bit at index to 1. Does nothing if the index is out of bounds.

pub fn flip(&mut self, index: u8)

Flips the bit at index. Does nothing if the index is out of bounds.

pub fn flip_all(&mut self)

Flips all bits in the bitset (0s become 1s, and 1s become 0s).

pub fn and_not(&mut self, other: Self)

In-place Difference / Mask-Clear. Clears any bits that are set in other. This represents the mathematical operation: self = self AND NOT other.

pub fn test(&self, index: u8) -> bool

Tests if the bit at index is 1. Returns false if the bit is 0 or index is out of bounds.

pub const fn count_ones(&self) -> u32

Returns the number of set bits (population count).

pub const fn leading_zeros(&self) -> u32

Returns the number of leading zeros in the bitset, counting from the most significant bit (index 127).

pub const fn is_empty(&self) -> bool

Returns true if no bits are set.

pub const fn last_set(&self) -> Option<u8>

Returns the highest index set, or None if the bitset is empty. Useful for finding the “top” of a priority queue or resource map.

pub const fn is_superset(&self, other: &Self) -> bool

Returns true if this bitset contains all the bits set in other.

pub const fn is_subset(&self, other: &BitSet128) -> bool

Returns true if this bitset is a subset of other.

pub const fn intersects(&self, other: &Self) -> bool

Returns true if this bitset shares at least one common set bit with other. Returns false if there is no overlap or if either bitset is empty.

pub fn iter(&self) -> BitSet128Iter

Returns an iterator over the indices of the set bits.
