A Collection contains serializable objects which are accessible by a key.

Required methods

fn put<T>(&mut self, key: &str, value: T) -> Result<Option<T>, Error> where
    T: Serialize + DeserializeOwned, 

Put the given value into the collection under the given key. If the key already exists, it’s replaced with the given value and the old value is returned.

fn get<T>(&mut self, key: &str) -> Result<Option<T>, Error> where
    T: Serialize + DeserializeOwned, 

fn prefix<'a, T>(
    &mut self,
    prefix: &str
) -> Box<dyn Iterator<Item = Result<T, Error>> + 'a> where
    T: Serialize + DeserializeOwned + 'a, 

Find all the files that have the given prefix and iterate over them.
