Struct sdset::multi::Intersection

pub struct Intersection<'a, T: 'a> { /* fields omitted */ }

Represent the intersection set operation that will be applied to the slices.

Note that the intersection is all the elements that are in all the slices at the same time.

Examples

use sdset::multi::OpBuilder;
use sdset::{SetOperation, Set, SetBuf};

let a = Set::new(&[1, 2, 4])?;
let b = Set::new(&[2, 3, 4, 5, 7])?;
let c = Set::new(&[2, 4, 6, 7])?;

let op = OpBuilder::from_vec(vec![a, b, c]).intersection();

let res: SetBuf<i32> = op.into_set_buf();
assert_eq!(&res[..], &[2, 4]);

Methods

impl<'a, T> Intersection<'a, T>

pub fn new(slices: Vec<&'a Set<T>>) -> Self

Construct one with slices checked to be sorted and deduplicated.

Trait Implementations

impl<'a, T: Clone + 'a> Clone for Intersection<'a, T>

fn clone(&self) -> Intersection<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Ord + Clone> SetOperation<&'a T, T> for Intersection<'a, T>

fn extend_vec(self, output: &mut Vec<T>)

Extend a Vec with the values of the Sets using this set operation.

fn into_set_buf(self) -> SetBuf<U>

Create a SetBuf using the SetOperation::extend_vec method.

impl<'a, T: Ord> SetOperation<&'a T, &'a T> for Intersection<'a, T>

fn extend_vec(self, output: &mut Vec<&'a T>)

Extend a Vec with the values of the Sets using this set operation.

fn into_set_buf(self) -> SetBuf<U>

Create a SetBuf using the SetOperation::extend_vec method.
