5/// Represents some action that can be cached.
6///
7/// The action has one associated type called [`Value`]. This is the value of data that this action
8/// returns. That data is cached, so that future invocations of this item can reuse the previously
9/// computed data.
10///
11/// The cached data here can be anything, but typically is a network request. The resulting value
12/// is typically the response type of the network request.
