Struct BitSet64 

pub struct BitSet64(/* private fields */);

A fixed-size bit set backed by a single u64. Supports positions 0..63.

Implementations

impl BitSet64

pub const fn empty() -> Self

Empty set.

pub const fn full() -> Self

Full set (all 64 bits set).

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

Set the bit at pos.

pub fn clear(&mut self, pos: u8)

Clear the bit at pos.

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

Test whether the bit at pos is set.

pub fn count(&self) -> u32

Return the number of set bits.

pub fn is_empty(&self) -> bool

Return true if no bits are set.

pub fn and(self, other: Self) -> Self

Compute bitwise AND.

pub fn or(self, other: Self) -> Self

Compute bitwise OR.

pub fn xor(self, other: Self) -> Self

Compute bitwise XOR.

pub fn not(self) -> Self

Compute bitwise NOT.

pub fn iter_ones(self) -> impl Iterator<Item = u8>

Iterate over set bit positions.

Trait Implementations

impl Clone for BitSet64

fn clone(&self) -> BitSet64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BitSet64

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

Formats the value using the given formatter.

impl Default for BitSet64

fn default() -> BitSet64

Returns the “default value” for a type.

impl PartialEq for BitSet64

fn eq(&self, other: &BitSet64) -> 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.
