Struct intmap::IntMap

pub struct IntMap<V> { /* fields omitted */ }

Methods

impl<V> IntMap<V>

pub fn new() -> Self

Creates a new IntMap.

Examples

use intmap::IntMap;

let mut map: IntMap<u64> = IntMap::new();

pub fn with_capacity(capacity: usize) -> Self

Creates a new IntMap with at least the given capacity, rounded to the next power of two.

Examples

use intmap::IntMap;

let mut map: IntMap<u64> = IntMap::with_capacity(20);

pub fn reserve(&mut self, additional: usize)

Ensures that the IntMap has space for at least additional more elements

pub fn insert(&mut self, key: u64, value: V) -> bool

Insert key/value into the IntMap.

Examples

use intmap::IntMap;

let mut map = IntMap::new();
map.insert(21, "Eat my shorts");

pub fn get(&self, key: u64) -> Option<&V>

Get value from the IntMap.

Examples

use intmap::IntMap;

let mut map: IntMap<u64> = IntMap::new();
map.insert(21, 42);
let val = map.get(21);
assert!(val.is_some());
assert_eq!(*val.unwrap(), 42);
assert!(map.contains_key(21));

pub fn get_mut(&mut self, key: u64) -> Option<&mut V>

Get mutable value from the IntMap.

Examples

use intmap::IntMap;

let mut map: IntMap<u64> = IntMap::new();
map.insert(21, 42);

assert_eq!(*map.get(21).unwrap(), 42);
assert!(map.contains_key(21));

{
    let mut val = map.get_mut(21).unwrap();
    *val+=1;
}
    assert_eq!(*map.get(21).unwrap(), 43);

pub fn remove(&mut self, key: u64) -> Option<V>

Remove value from the IntMap.

Examples

use intmap::IntMap;

let mut map: IntMap<u64> = IntMap::new();
map.insert(21, 42);
let val = map.remove(21);
assert!(val.is_some());
assert_eq!(val.unwrap(), 42);
assert!(!map.contains_key(21));

pub fn contains_key(&self, key: u64) -> bool

Returns true if key is in map.

Examples

use intmap::IntMap;

let mut map: IntMap<u64> = IntMap::new();
map.insert(21, 42);
assert!(map.contains_key(21));

pub fn clear(&mut self)

Removes all elements from map.

Examples

use intmap::IntMap;

let mut map: IntMap<u64> = IntMap::new();
map.insert(21, 42);
map.clear();
assert_eq!(map.len(), 0);

pub fn is_empty(&mut self) -> bool

Returns true if map is empty

Examples

use intmap::IntMap;

let mut map: IntMap<u64> = IntMap::new();
map.insert(21, 42);
assert!(!map.is_empty());
map.remove(21);
assert!(map.is_empty());

pub fn iter(&self) -> Iter<u64, V>

pub fn iter_mut(&mut self) -> IterMut<u64, V>

pub fn keys(&self) -> Keys<u64, V>

pub fn values(&self) -> Values<u64, V>

pub fn values_mut(&mut self) -> ValuesMut<u64, V>

pub fn drain(&mut self) -> Drain<u64, V>

pub fn len(&self) -> usize

Number of elements in map.

pub fn load(&self) -> u64

Force count number of slots filled.

pub fn load_rate(&self) -> f64

pub fn capacity(&self) -> usize

Total number of slots available.

pub fn assert_count(&self) -> bool

pub fn collisions(&self) -> IntMap<u64>
