Shorthand for `Clone + Send + Sync + 'static`, which makes returning `impl Trait` far easier from capsules, where `Trait` is often a `Fn(Foo) -> Bar`.

Capsules are blueprints for creating some immutable data and do not actually contain any data themselves. See the documentation for more. TODO(Gregor

The handle given to [`Capsule`]s in order to [`Capsule::build`] their [`Capsule::Data`]. See [`CapsuleReader`] and [`SideEffectRegistrar`] for more.

A list of capsules. This is either a singular capsule, like `count`, or a tuple, like `(foo, bar)`.

This struct is completely typeless in order to avoid *a lot* of dynamic dispatch that we used to have when dealing with the graph nodes. We avoid need

Represents a handle onto a particular listener, as created with `Container::listen()`. This struct doesn't do anything other than implement [`Drop`],

Represents a side effect that can be utilized within the build function. The key observation about side effects is that they form a tree, where each s
