Storage trait

Required Methods

fn set(&mut self, key: Vec<u8>, value: Vec<u8>) -> Option<Vec<u8>>

set K for V

fn get(&self, key: &[u8]) -> Option<Vec<u8>>

get V by K

use Vec<u8> as return because some implementation is hard to return &[u8]

fn remove(&mut self, key: &[u8]) -> Option<Vec<u8>>

Remove a key
