A basic example of hash collision using two strings: ```rust use std::{ collections::hash_map::DefaultHasher, hash::{Hash, Hasher}, };
const DEFAULT_CAPACITY: u64 = 17;
fn hash
fn main() {
/*
When passed through the hash
function, orange
and blueberry
both equal 8
*/
let a = hash("orange");
let b = hash("blueberry");
/*
If *collision* isn't handled, then the *value* ("orange") at the location of
the *key* (`8`) would be replaced with the *value* ("blueberry")
*/
assert_eq!(a, b)
}
Here, collision is completely handled due to *separate chaining*/*open addressing*:
rust
use implhm::SCHashMap;
fn main() { let mut map = SCHashMap::new();
map.insert("orange", "ORANGE");
map.insert("blueberry", "BLUEBERRY");
/*
In the case of *separate chaining*, collision is handled by placing any key-pairs
that calculate to the same hash into an ordered list at that index.
*/
assert_eq!(map.get("orange"), Some("ORANGE"));
assert_eq!(map.get("blueberry"), Some("BLUEBERRY"));
} ```
There are several different methods for handling collision. implhm provides the most basic implementations. The following features are available:
