Version of a function. For details about the concept, see Function versions.

Field	Description
id	string ID of the version.
functionId	string ID of the function that the version belongs to.
description	string Description of the version.
createdAt	string (date-time) Creation timestamp for the version. String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
runtime	string ID of the runtime environment for the function. Supported environments and their identifiers are listed in the Runtime environments.
entrypoint	string Entrypoint for the function: the name of the function to be called as the handler. Specified in the format `<function file name>.<handler name>`, for example, `index.myFunction`.
resources	Resources Resources allocated to the version.
executionTimeout	string (duration) Timeout for the execution of the version. If the timeout is exceeded, Cloud Functions responds with a 504 HTTP code.
serviceAccountId	string ID of the service account associated with the version.
imageSize	string (int64) Final size of the deployment package after unpacking.
status	enum (Status) Status of the version. `STATUS_UNSPECIFIED` `CREATING`: Version is being created. `ACTIVE`: Version is ready to use. `OBSOLETE`: Version will be deleted soon. `DELETING`: Version is being deleted.
tags[]	string Version tags. For details, see Version tag.
environment	string Environment settings for the version.
