gstore

Global and local state management for GTK apps which implements the flux pattern. This crate targets apps written with gtk-rust-app framework.

A State can be any kind of data structure an application is based on. For a 'counter' app it might be a struct with a single u32 field. Actions are enums which represent the possible features of the app affecting the state.

Global store usage

```rust

// Given you have a global state

[derive(Debug, Default, Clone, PartialEq, Eq)]

pub struct State { pub numbers: Vec }

// Using the store macro a 'store' for this state store!(State); // The following public interface will be generated:

pub type Store = gstore::Store /// Initialize the store and global state /// /// # Arguments /// - initializer: Initialize the state. /// - reducer: Handle actions and mutate the state /// - middlewares: Pre- and post-reduce handlers pub fn init_store( initializer: impl Fn(&mut State), reducer: impl Fn(gstore::Action, &mut State), middleware: Vec>> ) /// Get a static reference to the store pub fn store() -> &'static Store ```
