package main
import (
"errors"
"fmt"
"log"
"reflect"
"github.com/ooni/probe-engine/pkg/kvstore"
)
func main() {
kvs := &kvstore.Memory{}
if _, err := kvs.Get("akey"); !errors.Is(err, kvstore.ErrNoSuchKey) {
log.Fatal("unexpected error", err)
}
val := []byte("value")
if err := kvs.Set("akey", val); err != nil {
log.Fatal("unexpected error", err)
}
out, err := kvs.Get("akey")
if err != nil {
log.Fatal("unexpected error", err)
}
fmt.Printf("%+v\n", reflect.DeepEqual(val, out))
}
Output: true
