Trait Store

pub trait Store<K, V>: RawStore<K, V> {
    type Entry<'a>: RawEntry<'a, Key = K, Value = V>
       where Self: 'a;

    // Required methods
    fn entry(&mut self, key: K) -> Self::Entry<'_>;
    fn insert(&mut self, key: K, value: V) -> Option<V>;
}

the [KeyValue] trait extends the [RawKeyValue] trait to provide additional methods for manipulating key-value stores.

Required Associated Types

type Entry<'a>: RawEntry<'a, Key = K, Value = V> where Self: 'a

the entry for the key-value pair

Required Methods

fn entry(&mut self, key: K) -> Self::Entry<'_>

returns the [Entry] for the given key

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

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.

Implementations on Foreign Types

impl<K, V> Store<K, V> for BTreeMap<K, V>

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

impl<K, V, S> Store<K, V> for HashMap<K, V, S>

where K: Eq + Hash, S: BuildHasher,

type Entry<'a> = Entry<'a, K, V> where Self: 'a
