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

// Given you have a global state
#[derive(Debug, Default, Clone, PartialEq, Eq)]
pub struct State {
    pub numbers: Vec<u128>
}

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

pub type Store = gstore::Store<State>
/// 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<Box<dyn gstore::Middleware<State>>>
)
/// Get a static reference to the store
pub fn store() -> &'static Store
