-# Singletons
-
-The `app` attribute is aware of [`owned-singleton`] crate and its [`Singleton`]
-attribute. When this attribute is applied to one of the resources the runtime
-will perform the `unsafe` initialization of the singleton for you, ensuring that
-only a single instance of the singleton is ever created.

-[`Singleton`]: ../../api/owned_singleton_macros/attr.Singleton.html
-
-Note that when using the `Singleton` attribute you'll need to have the
-`owned_singleton` in your dependencies.
-
-Below is an example that uses the `Singleton` attribute on a chunk of memory
-and then uses the singleton instance as a fixed-size memory pool using one of
-the [`alloc-singleton`] abstractions.
