import "github.com/syndtr/goleveldb/leveldb" func main() { // Open the database db, err := leveldb.OpenFile("path/to/db", nil) if err != nil { log.Fatal(err) } defer db.Close() // Get the value of a key key := []byte("mykey") value, err := db.Get(key, nil) if err != nil { log.Fatal(err) } fmt.Printf("Value for key %s is %s\n", key, value) }This example demonstrates how to open a LevelDB database and retrieve the value of a key. The DB.Get method takes two arguments - the key and an optional read options parameter. In this example, we are passing nil for the read options parameter. In summary, the goleveldb.leveldb package is a LevelDB implementation written in Go. We can use the DB Get method to retrieve the value of a key from a LevelDB database.
