Struct census::TrackedObject

pub struct TrackedObject<T> { /* fields omitted */ }

Your tracked object.

A tracked object contains reference counting logic and an Arc to your object.

It is cloneable but calling clone will not clone your internal object.

Your object cannot be mutated. You can borrow it using the Deref interface.

Methods

impl<T> TrackedObject<T>

pub fn map<F>(&self, f: F) -> TrackedObject<T> where
    F: FnOnce(&T) -> T, 

Creates a new object from an existing one.

The new object will be registered in your original object's inventory.

let inventory = Inventory::new();

let seven = inventory.track(7);
let fourteen = seven.map(|i| i * 2);
assert_eq!(*fourteen, 14);

let living_instances = inventory.list();
assert_eq!(living_instances.len(), 2);
