+/**
+ * Actions can return an object containing the two properties defined in this interface. Both are optional.
+ * - update: An action can have a parameter. This method will be called whenever that parameter changes,
+ *   immediately after Svelte has applied updates to the markup. `ActionReturn` and `ActionReturn<undefined>` both
+ *   mean that the action accepts no parameters.
+ * - destroy: Method that is called after the element is unmounted
+ *
+ * Additionally, you can specify which additional attributes and events the action enables on the applied element.
+ * This applies to TypeScript typings only and has no effect at runtime.
+ *
+ * Example usage:
+ * ```ts
+ * interface Attributes {
+ * 	newprop?: string;
+ * 	'on:event': (e: CustomEvent<boolean>) => void;
+ * }
+ *
+ * export function myAction(node: HTMLElement, parameter: Parameter): ActionReturn<Parameter, Attributes> {
+ * 	// ...
+ * 	return {
+ * 		update: (updatedParameter) => {...},
+ * 		destroy: () => {...}
+ * 	};
+ * }
+ * ```
+ */
+export interface ActionReturn<
+	Parameter = undefined,
+	Attributes extends Record<string, any> = Record<never, any>
+> {
+	update?: (parameter: Parameter) => void;
+	destroy?: () => void;
+	/**
+	 * ### DO NOT USE THIS
+	 * This exists solely for type-checking and has no effect at runtime.
+	 * Set this through the `Attributes` generic instead.

+/**
+ * Actions are functions that are called when an element is created.
+ * You can use this interface to type such actions.
+ * The following example defines an action that only works on `<div>` elements
+ * and optionally accepts a parameter which it has a default value for:
+ * ```ts
+ * export const myAction: Action<HTMLDivElement, { someProperty: boolean } | undefined> = (node, param = { someProperty: true }) => {
+ *   // ...
+ * }
+ * ```
+ * `Action<HTMLDivElement>` and `Action<HTMLDivElement, undefined>` both signal that the action accepts no parameters.
+ *
+ * You can return an object with methods `update` and `destroy` from the function and type which additional attributes and events it has.
+ * See interface `ActionReturn` for more details.
