Enum MenuDirectionType 

#[non_exhaustive]
pub enum MenuDirectionType {
    Parent,
    Child,
    Next,
    Prev,
}

An enumeration representing directional movements within a menu.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Parent

To the parent menu shell

Child

To the submenu, if any, associated with the item

Next

To the next menu item

Prev

To the previous menu item
