Struct hibitset::BitSetAnd

pub struct BitSetAnd<A: BitSetLike, B: BitSetLike>(pub A, pub B);

BitSetAnd takes two BitSetLike items, and merges the masks returning a new virtual set, which represents an intersection of the two original sets.

Trait Implementations

impl<A: BitSetLike, B: BitSetLike> BitSetLike for BitSetAnd<A, B>

fn layer3(&self) -> usize

Return a usize where each bit represents if any word in layer2 has been set.

fn layer2(&self, i: usize) -> usize

Return the usize from the array of usizes that indicates if any bit has been set in layer1

fn layer1(&self, i: usize) -> usize

Return the usize from the array of usizes that indicates if any bit has been set in layer0

fn layer0(&self, i: usize) -> usize

Return a usize that maps to the direct 1:1 association with each index of the set

fn contains(&self, i: u32) -> bool

Allows checking if set bit is contained in the bit set.

fn get_from_layer(&self, layer: usize, idx: usize) -> usize

Gets the usize corresponding to layer and index.

fn is_empty(&self) -> bool

Returns true if this BitSetLike contains nothing, and false otherwise.
