label property

String? label
getter/setter pair

Possible string values are:

  • "LABEL_OPTIONAL" : 0 is reserved for errors
  • "LABEL_REPEATED"
  • "LABEL_REQUIRED" : The required label is only allowed in proto2. In proto3 and Editions it's explicitly prohibited. In Editions, the field_presence feature can be used to get this behavior.

Implementation

core.String? label;
