Crate arraysetcell

Source
Expand description

ArraySetCell is a fixed-capacity, vector-like array with interior mutability and no ordering guarantees. Elements are stored as Cell<Option<T>>

use std::cell::Cell;
use arraysetcell::ArraySetCell;

let mut array = ArraySetCell::<u32, 3>::from([Some(1), None, Some(3)]);
assert_eq!(array.capacity(), 3);
assert_eq!(array.len(), 2);

array.push(10);
assert_eq!(array.len(), 3);

array.retain(|x| *x < 10);
assert_eq!(array.len(), 2);

let result = array.filter_mut(|x| if *x > 2 { Some(*x) } else { None });
assert_eq!(result, Some(3));

let mut iter = array.into_iter();
assert_eq!(iter.size_hint(), (2, Some(2)));
assert_eq!(iter.next(), Some(1));
assert_eq!(iter.next(), Some(3));
assert_eq!(iter.next(), None);
