1/// Whether the entry is toggleable, and if so, whether it is currently toggled.
 2///
 3/// To make an element toggleable, simply add a `Toggle::Toggled(_)` and handle it's cases.
 4///
 5/// You can check if an element is toggleable with `.is_toggleable()`
 6///
 7/// Possible values:
 8/// - `Toggle::NotToggleable` - The entry is not toggleable
 9/// - `Toggle::Toggled(true)` - The entry is toggleable and toggled
10/// - `Toggle::Toggled(false)` - The entry is toggleable and not toggled
