pub struct BitSet<T> {
    domain_size: usize,
    words: Vec<u64>,
    marker: PhantomData<T>,
}
Expand description

A fixed-size bitset type with a dense representation.

NOTE: Use GrowableBitSet if you need support for resizing after creation.

T is an index type, typically a newtyped usize wrapper, but it can also just be usize.

All operations that involve an element will panic if the element is equal to or greater than the domain size. All operations that involve two bitsets will panic if the bitsets have differing domain sizes.

Fields

domain_size: usizewords: Vec<u64>marker: PhantomData<T>

Implementations

Gets the domain size.

Creates a new, empty bitset with a given domain_size.

Creates a new, filled bitset with a given domain_size.

Clear all elements.

Clear excess bits in the final word.

Count the number of set bits in the set.

Returns true if self contains elem.

Is self is a (non-strict) superset of other?

Is the set empty?

Insert elem. Returns whether the set has changed.

Sets all bits to true.

Returns true if the set has changed.

Gets a slice of the underlying words.

Iterates over the indices of set bits in a sorted order.

Duplicates the set as a hybrid set.

Set self = self | other. In contrast to union returns true if the set contains at least one bit that is not in other (i.e. other is not a superset of self).

This is an optimization for union of a hybrid bitset.

Sets self = self | other and returns true if self changed (i.e., if new bits were added).

Sets self = self - other and returns true if self changed. (i.e., if any bits were removed).

Sets self = self & other and return true if self changed. (i.e., if any bits were removed).

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
