Trait SliceStorage 

pub trait SliceStorage<K, V>: Default {
    // Required methods
    fn insert(&mut self, value: V) -> K;
    fn remove(&mut self, key: K) -> Option<V>;
    fn get(&self, key: K) -> Option<&V>;
    fn iter(&self) -> Box<dyn Iterator<Item = (K, &V)> + '_>;
    fn values(&self) -> Box<dyn Iterator<Item = &V> + '_>;
    fn values_mut(&mut self) -> Box<dyn Iterator<Item = &mut V> + '_>;
    fn is_empty(&self) -> bool;
}

Trait to abstract operations on storage of slices

Required Methods

fn insert(&mut self, value: V) -> K

fn remove(&mut self, key: K) -> Option<V>

fn get(&self, key: K) -> Option<&V>

fn iter(&self) -> Box<dyn Iterator<Item = (K, &V)> + '_>

fn values(&self) -> Box<dyn Iterator<Item = &V> + '_>

fn values_mut(&mut self) -> Box<dyn Iterator<Item = &mut V> + '_>

fn is_empty(&self) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
