Trait SharedBitSet

pub trait SharedBitSet<T> {
    // Required methods
    fn clear(&self);
    fn insert(&self, index: T) -> Option<bool>;
    fn remove(&self, index: T) -> Option<bool>;
}

A trait for updating values in a shared bit-set.

Required Methods

fn clear(&self)

Clears the set

Example

use index_set::{SharedBitSet, BitSet};
use std::sync::atomic::AtomicU32;

let mut bitset: [AtomicU32; 4] = Default::default();
bitset.insert(0);
assert!(!BitSet::is_empty(&bitset[..]));

bitset.clear();
assert!(BitSet::is_empty(&bitset[..]));

fn insert(&self, index: T) -> Option<bool>

Inserts the index into the set Returns true if the index was not already set

Example

use index_set::{SharedBitSet, BitSet};
use std::sync::atomic::AtomicU32;

let mut bitset: [AtomicU32; 4] = Default::default();
bitset.insert(0);
assert_eq!(bitset.has(0), true);

fn remove(&self, index: T) -> Option<bool>

Removes the index from the set Returns true if the index was set.

Example

use index_set::{SharedBitSet, BitSet};
use std::sync::atomic::AtomicU32;

let mut bitset: [AtomicU32; 4] = Default::default();
bitset.insert(42);
assert_eq!(bitset.has(42), true);

bitset.remove(42);
assert_eq!(bitset.has(42), false);
