Trait Collection 

pub trait Collection<'a, T>
where
    T: Serialize + DeserializeOwned + 'a,
{
    // Required methods
    fn put(&mut self, key: &str, value: T) -> Result<Option<T>, Error>;
    fn get(&mut self, key: &str) -> Result<Option<T>, Error>;
    fn prefix(
        &mut self,
        prefix: &str,
    ) -> Box<dyn Iterator<Item = Result<T, Error>> + 'a>;
}

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

Required Methods

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

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(&mut self, key: &str) -> Result<Option<T>, Error>

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

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