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;letmut objects = FlattenObjects::<u32,20>::new();// Add `23` 10 times and assign them IDs from 0 to 9.for i in0..=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));
