An Operation resource. For more information, see Operation.

Field

Description

id

string

ID of the operation.

description

string

Description of the operation. 0-256 characters long.

createdAt

string (date-time)

Creation timestamp.

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).

createdBy

string

ID of the user or service account who initiated the operation.

modifiedAt

string (date-time)

The time when the Operation resource was last modified.

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).

done

boolean

If the value is false, it means the operation is still in progress.
If true, the operation is completed, and either error or response is available.

metadata

CreateSymmetricKeyMetadata

Service-specific metadata associated with the operation.
It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any.

error

Status

The error result of the operation in case of failure or cancellation.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

response

SymmetricKey

The normal response of the operation in case of success.
If the original method returns no data on success, such as Delete,
the response is google.protobuf.Empty.
If the original method is the standard Create/Update,
the response should be the target resource of the operation.
Any method that returns a long-running operation should document the response type, if any.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

CreateSymmetricKeyMetadata

Description

keyId

string
