# chicken-sublevel

Provides easy namespacing of keys inside a single LevelDB database. This is
an implementation of the [level](https://github.com/caolan/chicken-level)
API.

## Example use

```scheme
(use level leveldb sublevel lazy-seq)

(define db (open-db "./my-database"))

(define books (sublevel db '("books")))
(define cds (sublevel db '("music" "cds")))

(db-put books "book1" "foo")
(db-put books "book2" "bar")

(lazy-seq->list (db-stream books)) ;; => (("book1" "foo") ("book2" "bar"))
(lazy-seq->list (db-stream cds)) ;; => ()
```

## API

### sublevel

```scheme
(sublevel db prefix)
```

Wraps a level implementation with namespaced access. Keys are generated by
joining name space strings with the `null` character.
