fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K: Hash + Eq, V: ?Sized> Default for Cachr<K, V>

fn default() -> Self

Returns the “default value” for a type.

impl<K, V: ?Sized> From<HashMap<K, Box<V, Global>, RandomState>> for Cachr<K, V>

fn from(hashmap: HashMap<K, Box<V>>) -> Self

Converts to this type from the input type.

impl<K: Hash + Eq, V: ?Sized> Index<K> for Cachr<K, V>

type Output = V
