flatten_objects
FlattenObjects
is a container that stores numbered objects.
Objects can be added to the FlattenObjects
, a unique ID will be assigned
to the object. The ID can be used to retrieve the object later.
Example
use flatten_objects::FlattenObjects;
let mut objects = FlattenObjects::<u32, 20>::new();
// Add `23` 10 times and assign them IDs from 0 to 9.
for i in 0..=9 {
objects.add_at(i, 23).unwrap();
assert!(objects.is_assigned(i));
}
// Remove the object with ID 6.
assert_eq!(objects.remove(6), Some(23));
assert!(!objects.is_assigned(6));
// Add `42` (the ID 6 is available now).
let id = objects.add(42).unwrap();
assert_eq!(id, 6);
assert!(objects.is_assigned(id));
assert_eq!(objects.get(id), Some(&42));
assert_eq!(objects.remove(id), Some(42));
assert!(!objects.is_assigned(id));
