How can I use prefix query？

[dermesser]

Try this (and close the issue if it works, please):

• get an iterator (https://docs.rs/rusty-leveldb/latest/rusty_leveldb/struct.DB.html#method.new_iter)
• seek() to the prefix you are interested in (https://docs.rs/rusty-leveldb/latest/rusty_leveldb/trait.LdbIterator.html#tymethod.seek)
• and keep iterating until the prefix changes.
