Struct ElementMask 

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

The set of elements present, one bit per atomic number.

The periodic table fits in two machine words, so membership is a shift and a test rather than a search.

Implementations

impl ElementMask

pub const EMPTY: Self

The empty set.

pub const fn insert(&mut self, element: Element)

Adds an element.

pub const fn contains(self, element: Element) -> bool

Returns true when the element may be present.

pub const fn is_empty(self) -> bool

Returns true when the set is empty.

pub const fn union_with(&mut self, other: Self)

Adds everything in other.

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

Returns true when the two sets share an element.

pub const fn len(self) -> u32

The number of distinct elements.
