A trait representing a collection of key-value pairs in a database.

Required Methods

fn get(&self, key: &str) -> Result<Vec<u8>, Error>

Retrieves the value associated with the given key.

fn put(&self, key: &str, data: Vec<u8>) -> Result<(), Error>

Associates the given value with the given key.

fn del(&self, key: &str) -> Result<(), Error>

Removes the value associated with the given key.

fn iter<'a>( &'a self, reverse: bool, prefix: String ) -> Box<dyn Iterator<Item = (String, Vec<u8>)> + 'a>

Returns an iterator over the key-value pairs in the collection.
