Struct oasis_std::collections::set::Set

pub struct Set<T> { /* fields omitted */ }

Set is a data structure with a Set-like API but based on a Vec. It's primarily useful when you care about constant factors or prefer determinism to speed. Please refer to the docs for Set for details and examples of the Set API.

Example

use oasis_std::collections::Set;
let mut set1 = Set::new();
let mut set2 = Set::new();
set1.insert(1);
set1.insert(2);
set2.insert(2);
set2.insert(3);
let mut set3 = Set::with_capacity(1);
assert!(set3.insert(3));
assert_eq!(&set2 - &set1, set3);
