You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: types.go
    path of file: ./repos/chat/server/store/types
    
    the code of the file until where you have to start completion: // Package types provides data types for persisting objects in the databases.
package types

	"database/sql/driver"
	"encoding/base32"
	"encoding/base64"
	"encoding/binary"
	"encoding/json"
	"errors"
	"sort"
	"strings"
	"time"
)

// StoreError satisfies Error interface but allows constant values for
// direct comparison.
type StoreError string

// Error is required by error interface.
func (s StoreError) Error() string {
	return string(s)
}

const (
	// ErrInternal means DB or other internal failure.
	ErrInternal = StoreError("internal")
	// ErrMalformed means the secret cannot be parsed or
