tui-dispatch 0.7.0

//! tui-dispatch: Centralized state management for Rust TUI apps
//!
//! Like Redux/Elm, but for terminals. Components are pure functions of state,
//! and all state mutations happen through dispatched actions.
//!
//! # Quick Start
//!
//! ```
//! use tui_dispatch::prelude::*;
//!
//! // Define your actions
//! #[derive(Action, Clone, Debug)]
//! enum MyAction {
//!     Increment,
//!     Decrement,
//!     Quit,
//! }
//!
//! // Define your state
//! #[derive(Default)]
//! struct MyState {
//!     count: i32,
//! }
//!
//! // Write a reducer
//! fn reducer(state: &mut MyState, action: MyAction) -> ReducerResult {
//!     match action {
//!         MyAction::Increment => { state.count += 1; ReducerResult::changed() }
//!         MyAction::Decrement => { state.count -= 1; ReducerResult::changed() }
//!         MyAction::Quit => ReducerResult::unchanged(),
//!     }
//! }
//!
//! // Create a store
//! let mut store = Store::new(MyState::default(), reducer);
//! store.dispatch(MyAction::Increment);
//! assert_eq!(store.state().count, 1);
//! ```
//!
//! # With Effects
//!
//! For async operations, return effects from the same `Store` reducer:
//!
//! ```
//! use tui_dispatch::prelude::*;
//!
//! #[derive(Action, Clone, Debug)]
//! enum Action {
//!     Fetch,
//!     DidLoad(String),
//! }
//!
//! enum Effect {
//!     FetchData,
//! }
//!
//! #[derive(Default)]
//! struct State {
//!     data: Option<String>,
//!     loading: bool,
//! }
//!
//! fn reducer(state: &mut State, action: Action) -> ReducerResult<Effect> {
//!     match action {
//!         Action::Fetch => {
//!             state.loading = true;
//!             ReducerResult::changed_with(Effect::FetchData)
//!         }
//!         Action::DidLoad(data) => {
//!             state.data = Some(data);
//!             state.loading = false;
//!             ReducerResult::changed()
//!         }
//!     }
//! }
//!
//! let mut store = Store::new(State::default(), reducer);
//! let result = store.dispatch(Action::Fetch);
//! assert!(result.changed);
//! assert_eq!(result.effects.len(), 1);
//! ```
//!
//! See the [documentation](https://docs.rs/tui-dispatch) for full guides.
