Module features 

Runtime feature flags for TUI applications

Feature flags allow you to toggle functionality at runtime, useful for:

• Gradual feature rollouts
• A/B testing
• Debug-only features
• User preferences

Quick Start

use tui_dispatch::FeatureFlags;

#[derive(FeatureFlags)]
struct Features {
    #[flag(default = false)]
    new_search_ui: bool,

    #[flag(default = true)]
    vim_bindings: bool,
}

let mut features = Features::default();
assert!(!features.new_search_ui);
assert!(features.vim_bindings);

features.enable("new_search_ui");
assert!(features.new_search_ui);

Usage in Reducers

fn reducer(state: &mut AppState, action: Action, features: &Features) -> bool {
    match action {
        Action::ShowSuggestions(s) if features.new_search_ui => {
            state.suggestions = s;
            true
        }
        Action::ShowSuggestions(_) => false, // Feature disabled
        // ...
    }
}

Usage in Render

if features.new_search_ui {
    render_new_search(frame, area, state);
} else {
    render_legacy_search(frame, area, state);
}
