Struct sdset::multi::Difference

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

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

Note that the difference is all the elements that are in the first slice but not in all the others.

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]).difference();

let res: SetBuf<i32> = op.into_set_buf();
assert_eq!(&res[..], &[1]);

Methods

impl<'a, T> Difference<'a, T>

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

Construct one with slices checked to be sorted and deduplicated.
