Crate beach_map

A BeachMap is just a SlotMap, a data structure used to store elements and access them with an id.

Example:

use beach_map::BeachMap;

let mut beach = BeachMap::default();
let id1 = beach.insert(1);
let id2 = beach.insert(2);

assert_eq!(beach.len(), 2);
assert_eq!(beach[id1], 1);

assert_eq!(beach.remove(id2), Some(2));
assert_eq!(beach.get(id2), None);
assert_eq!(beach.len(), 1);

beach[id1] = 7;
assert_eq!(beach[id1], 7);

beach.extend(1..4);

assert_eq!(beach.data(), [7, 1, 2, 3]);

You shouldn't assume the order of the elements as any removing operation will shuffle them.

Rayon

To use rayon with beach_map, you need rayon in your dependencies and add the parallel feature to beach_map.

Example:

use beach_map::BeachMap;
use rayon::prelude::*;

let mut beach = BeachMap::default();
let ids = beach.extend(0..500);

beach.par_iter_mut().for_each(|x| {
    *x *= 2;
});

for i in 0..ids.len() {
    assert_eq!(beach[ids[i]], i * 2);
}
