Module: Google::Api::FieldBehavior
- Defined in:
- proto_docs/google/api/field_behavior.rb
Overview
An indicator of the behavior of a given field (for example, that a field is required in requests, or given as output but ignored as input). This does not change the behavior in protocol buffers itself; it only denotes the behavior and may affect how API tooling handles the field.
Note: This enum may receive new values in the future.

- FIELD_BEHAVIOR_UNSPECIFIED =
Conventional default for enums. Do not use this.
0
- OPTIONAL =
Specifically denotes a field as optional. While all fields in protocol buffers are optional, this may be specified for emphasis if appropriate.
1
- REQUIRED =
Denotes a field as required. This indicates that the field must be provided as part of the request, and failure to do so will cause an error (usually
INVALID_ARGUMENT
). 2
- OUTPUT_ONLY =
Denotes a field as output only. This indicates that the field is provided in responses, but including the field in a request does nothing (the server must ignore it and must not throw an error as a result of the field's presence).
3
- INPUT_ONLY =
Denotes a field as input only. This indicates that the field is provided in requests, and the corresponding field is not included in output.
4
- IMMUTABLE =
Denotes a field as immutable. This indicates that the field may be set once in a request to create a resource, but may not be changed thereafter.
