Struct DomainBitset 

pub struct DomainBitset { /* private fields */ }

A simple bitset wrapped around a Vec<u64>.

This structure is used to track which entities have components in a specific SemanticDomain. It allows for extremely fast (bitwise) filtering during transversal queries.

Implementations

impl DomainBitset

pub fn new() -> Self

Creates a new, empty bitset.

pub fn set(&mut self, index: u32)

Sets the bit at the specified index to 1.

pub fn clear(&mut self, index: u32)

Clears the bit at the specified index to 0.

pub fn get_block(&self, word_idx: usize) -> u64

Returns the 64-bit block at the specified word index. Returns 0 if the index is out of bounds.

pub fn is_set(&self, index: u32) -> bool

Returns true if the bit at the specified index is set.

pub fn intersect(&mut self, other: &DomainBitset)

Performs a bitwise AND with another bitset.

Trait Implementations

impl Clone for DomainBitset

fn clone(&self) -> DomainBitset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DomainBitset

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

Formats the value using the given formatter.

impl Default for DomainBitset

fn default() -> DomainBitset
