Struct MultiIntersection 

pub struct MultiIntersection<S>
where
    S: SkippingSearch,
{ /* private fields */ }

Combines an arbitrary number of SkippingSearch objects, and returns only the items present in all of them.

Implementations

impl<S> MultiIntersection<S>

where S: SkippingSearch,

pub fn new(sub_searches: Vec<S>) -> Self

Assembles a multi-intersection out of other SkippingSearch objects.

Panics

Will panic if sub_searches.len() == 0

Trait Implementations

impl<S> SkippingSearch for MultiIntersection<S>

where S: SkippingSearch,

type Item = <S as SkippingSearch>::Item

fn suggest_next(&self) -> Option<Self::Item>

Returns the smallest value for which find_and_advance may return true. For efficiency reasons, making sure the value is one for which find_and_advance will return true is preferred, when possible.

fn find_and_advance(&mut self, item: &Self::Item) -> bool

Returns whether this contains the passed-in value. Also mutates the receiver to forget about any values smaller than or equal to the item.

fn size_hint(&self) -> (usize, Option<usize>)

Returns a lower/upper bound on the number of values that can be obtained by using self.find_and_advance(self.suggest_next()) repeatedly. (0, None) is a valid, minimally constraining answer. (n, Some(n)) is a maximally constraining answer.
