Trait IIndexAware 

pub trait IIndexAware {
    // Required methods
    fn index(&self) -> usize;
    fn set_index(&self, index: usize);
}

An item that knows its index in a sorted collection (IIndexAware), which UpdateIndex sets.

Deviation (DEVIATIONS.md, DynamicData): the setter takes &self, as the items are shared (Rc) and keep the index in a Cell; the index is a usize.

Required Methods

fn index(&self) -> usize

The index (Index).

fn set_index(&self, index: usize)

Sets the index (Index).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
