Documentation

Overview

Package store provides implementation of LevelDB key/value database.

Create or open a database:

// The returned DB instance is safe for concurrent use. Which mean that all
// DB's methods may be called concurrently from multiple goroutine.
db, err := store.NewStore("path/to/db")
...
defer db.Close()
...

Read or modify the database content:

// Remember that the contents of the returned slice should not be modified.
data := db.Get(key)
...
db.Put(key), []byte("value"))
...
db.Delete(key)
...
