Trait Selectable 

pub trait Selectable {
    // Required methods
    fn is_empty(&self) -> bool;
    fn len(&self) -> usize;
    fn next(&mut self);
    fn prev(&mut self);
    fn index(&self) -> usize;
    fn set_index(&mut self, index: usize);
    fn selected_is_last(&self) -> bool;
}

Allow selection of a element and basic navigation. Its implementation is mostly made by the macro crate::impl_selectable which allows to manipulate all sort of content in a common manner. It simplifies a lot the creation of menus for any action and is used everywhere.

Required Methods

fn is_empty(&self) -> bool

True iff the content is empty

fn len(&self) -> usize

Number of element in content

fn next(&mut self)

Select next element in content

fn prev(&mut self)

Select previous element in content

fn index(&self) -> usize

Current index of selected element. 0 if the content is empty (I know, could be an option)

fn set_index(&mut self, index: usize)

set the index to the value if possible

fn selected_is_last(&self) -> bool

true if the selected element is the last of content
