Struct fj_kernel::storage::Handle

pub struct Handle<T> { /* private fields */ }

A handle for an object

You can get an instance of Handle by inserting an object into a store. A handle dereferences to the object it points to, via its Deref implementation.

Equality and Identity

Equality of Handles is defined via the objects they reference. If those objects are equal, the Handles are considered equal.

This is distinct from the identity of the referenced objects. Two objects might be equal, but they might be have been created at different times, for different reasons, and thus live in different slots in the storage. This is a relevant distinction when validating objects, as equal but not identical objects might be a sign of a bug.

You can compare the identity of two objects through their Handles, by comparing the values returned by Handle::id.
