This enum is defined as #[non_exhaustive] because Google Cloud may add
additional enum variants at any time. Adding new variants is not considered
a breaking change. Applications should write their code in anticipation of:
New values appearing in future releases of the client library, and
New values received dynamically, without application changes.
Please consult the Working with enums section in the user guide for some
guidelines.
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Model is constrained to always predicting function calls only.
If “allowed_function_names” are set, the predicted function calls will be
limited to any one of “allowed_function_names”, else the predicted
function calls will be any one of the provided “function_declarations”.
