A Rust implementation of Redux.
Redux, originally implemented in JavaScript, is an functional approach to state management. The core concept is that you have a state and a reducer, a function to create a new state from the old one and an action, a description of what to change. Because the state itself is immutable, this results in a very clean way of managing application state, where every possible action is defined beforehand and dispatched later on.
