Trait ActionCategory 

pub trait ActionCategory: Action {
    type Category: Copy + Eq + Hash + Debug;

    // Required methods
    fn category(&self) -> Option<&'static str>;
    fn category_enum(&self) -> Self::Category;
}

Extension trait for actions with category support

This trait is auto-implemented when using #[derive(Action)] with #[action(infer_categories)]. It provides methods to query an action’s category for routing and filtering.

Example

use tui_dispatch::ActionCategory;

#[derive(Action, Clone, Debug)]
#[action(infer_categories)]
enum MyAction {
    SearchStart,
    SearchClear,
    ConnectionFormOpen,
}

let action = MyAction::SearchStart;
assert_eq!(action.category(), Some("search"));
assert!(matches!(action.category_enum(), MyActionCategory::Search));

Required Associated Types

type Category: Copy + Eq + Hash + Debug

The category enum type generated by the derive macro

Required Methods

fn category(&self) -> Option<&'static str>

Get the action’s category as a string (if categorized)

fn category_enum(&self) -> Self::Category

Get the action’s category as an enum value

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
