Struct Union

pub struct Union<'a, T: 'a> { /* private fields */ }

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

Examples

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

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

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

let res: SetBuf<i32> = op.into_set_buf();
assert_eq!(&res[..], &[1, 2, 3, 4, 5, 6, 7]);

Implementations

impl<'a, T> Union<'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 Union<'a, T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

fn extend_collection<C>(self, output: &mut C)

where C: Collection<&'a T>,

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

fn into_set_buf(self) -> SetBuf<T>

where T: Clone,
