Trait BitSetMut

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

A trait for a mutate values in a bit set.

Required Methods

fn clear(&mut self)

Clears the set

Example

use index_set::{BitSet, BitSetMut};

let mut bitset: [u32; 4] = [0; 4];
bitset.insert(0);
assert!(!BitSet::is_empty(&bitset[..]));

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

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

Inserts the value into the set.

Returns true if the value was already set. Returns None if the set cannot hold the value.

Example

use index_set::{BitSet, BitSetMut};

let mut bitset: [u32; 4] = [0; 4];
bitset.insert(0);
assert_eq!(bitset.has(0), true);

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

Removes the value from the set

Returns Some(true) if the value was already set. Returns None if the set cannot hold the value.

Example

use index_set::{BitSet, BitSetMut};

let mut bitset: [u32; 4] = [0; 4];
bitset.insert(42);
assert_eq!(bitset.has(42), true);

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