示例1: GetInitialSystemValues
// GetInitialSystemValues returns a list of key/value pairs.
// They are written at cluster bootstrap time (see storage/node.go:BootstrapCLuster).
func GetInitialSystemValues() []proto.KeyValue {
systemData := []struct {
parentID ID
desc descriptorProto
}{
{keys.RootNamespaceID, &SystemDB},
{SystemDB.ID, &NamespaceTable},
{SystemDB.ID, &DescriptorTable},
{SystemDB.ID, &UsersTable},
{SystemDB.ID, &ZonesTable},
}
// Initial kv pairs:
// - ID generator
// - 2 per table/database
numEntries := 1 + len(systemData)*2
ret := make([]proto.KeyValue, numEntries, numEntries)
i := 0
// Descriptor ID generator.
value := proto.Value{}
value.SetInteger(int64(keys.MaxReservedDescID + 1))
ret[i] = proto.KeyValue{
Key: keys.DescIDGenerator,
Value: value,
}
i++
// System database and tables.
for _, d := range systemData {
value = proto.Value{}
value.SetInteger(int64(d.desc.GetID()))
ret[i] = proto.KeyValue{
Key: MakeNameMetadataKey(d.parentID, d.desc.GetName()),
Value: value,
}
i++
value = proto.Value{}
if err := value.SetProto(d.desc); err != nil {
log.Fatalf("could not marshal %v", d.desc)
}
ret[i] = proto.KeyValue{
Key: MakeDescMetadataKey(d.desc.GetID()),
Value: value,
}
i++
}
return ret
}示例2: marshalValue
// marshalValue returns a proto.Value initialized from the source
// reflect.Value, returning an error if the types are not compatible.
func marshalValue(v reflect.Value) (proto.Value, error) {
var r proto.Value
if !v.IsValid() {
return r, nil
}

case nil:
return r, nil
case string:
r.Bytes = []byte(t)
return r, nil
case []byte:
r.Bytes = t
return r, nil
case proto.Key:
r.Bytes = []byte(t)
return r, nil
case gogoproto.Message:
var err error
r.Bytes, err = gogoproto.Marshal(t)
return r, err
case encoding.BinaryMarshaler:
var err error
r.Bytes, err = t.MarshalBinary()
return r, err
}
switch v.Kind() {
case reflect.Bool:
i := int64(0)
if v.Bool() {
i = 1
}
r.SetInteger(i)
return r, nil
case reflect.Int, reflect.Int8, reflect.Int16, reflect.Int32, reflect.Int64:
r.SetInteger(v.Int())
return r, nil
case reflect.Uint, reflect.Uint8, reflect.Uint16, reflect.Uint32, reflect.Uint64, reflect.Uintptr:
r.SetInteger(int64(v.Uint()))
return r, nil
case reflect.Float32, reflect.Float64:

return r, nil
case reflect.String:

return r, nil
}
return r, fmt.Errorf("unable to marshal value: %s", v)
